Program to calculate power of any number with user defined function

Monday, March 25, 2013 Basic C Programs No comments

Last time we calculated power of any number using inbuilt function power() declared in math.h here. But in this post we have our user defined power() function that works same as the built in function. Check this code: #include<stdio.h> #include<conio.h> int power(int,int); void main() { int x,n,result; printf("Enter number : \n"); scanf("%d",&x); printf("Enter power : \n"); scanf("%d",&n); result=power(x,n); printf("%d to the power %d is %d",x,n,result); getch(); } int power(int...

Program to use printf() without semicolon

Wednesday, March 20, 2013 Basic C Programs

A surprising program, printf() function call without semicolon !! Whenever we use a printf() function or any function which ends with semicolon ( ; ), and if we not place the semicolon at the end, then compiler gives an error like "Statement missing ;" Then how can we do this ?? Check this program which prints a static string without semicolon.. //Program which use no semicolon but prints an output using printf() function #include<stdio.h> void main() { if(printf("Hello")) { } } The logic behind is that, an if...

Program to calculate ACSII value of characters, digits and symbols

Wednesday, March 20, 2013 Basic C Programs

Most of character and string operations are based on ASCII values. ASCII value is standard value for every character, digit and symbol in C compiler. There are 128 ASCII values but Extended ASCII can represent 256 characters. A Complete ASCII Table: A really long chart, hmmm !! Don't worry you don't need to remember these all values. You can find common ASCII values using a simple logic. What you need to do is - Take a character variable...

Program to find length of a string

Wednesday, March 20, 2013 Basic C Programs

If we want to calculate number of characters in a string then it can be done with the help of a function strlen(). This function takes a string as argument and then return the number of characters in string. As we know that index of array always starts with 0 and every character string contains a NULL character ('\0') . So this function counts the indices of string until it gets the NULL character. Check this program- //Program to find length of a string //This program will show how to calculate that how many characters are there in...

Program to compare two strings

Wednesday, March 20, 2013 Basic C Programs

After reading about string. Now we are comparing two strings. It is very easy to compare two numbers using some comparison operators (>,<,>=,<=,==,!=). But if we are talking about strings, these operators are not generally applicable to them. If we want to manipulate a string then we can use some inbuilt functions of string.h header file. Here we are using strcmp() function to compare two strings. This function takes two strings as argument for their comparison.If both strings are equal then it returns 0. If first string...

Program to use string (Character array)

Wednesday, March 20, 2013 Basic C Programs

Before we use string we should have an idea about "What is a String ??" A string is just a character array and follows all the properties of array. If we declare an array with char datatype then it will be called a string. Syntax: char array_name[size/limit]; Here in above syntax you see, we are using char as datatype of the array. String also has size or limit for characters as an integer array has. String is used to store character input like name, addresses etc. We can get a string input using scanf() function with %s format specifier...

Program to calculate x to the power n using power function of math.h

Wednesday, March 20, 2013 Basic C Programs

A simple program to calculate power of a given number. We have an inbuilt power() function in math.h. This function takes two arguments. Example: temp=power(num,pow); In above example the power() function is taking two arguments. First argument is a number and second one is power() for that number. So this function will return num to the power pow. We are using a temporary variable to hold the result because power() function returns a value. We can use inbuilt math.h functions for basic mathematical calculations. For example we can use...

Program to implement Call by Reference (CBR)

Thursday, March 14, 2013 Basic C Programs

Before understanding call by reference, you should have an idea of call by value. When we passes reference of arguments to a function as actual argument and uses pointer in function definition as formal argument then it will be call by reference. Pointer: It is a type of variable which holds address/reference of another variable. The terms call by value and call by reference are used together. The difference is that in call by value, a copy of actual arguments is passed whereas in call by reference, reference (address) of arguments...

Program to Implement Call By Value (CBV)

Thursday, March 14, 2013 Basic C Programs

When we passes any argument to a function, a copy of the arguments is passed to the function. If we change value of the arguments in the function it will not affect the original arguments which are passed to the function. This is called Call by Value. The arguments which are passed to a function are known as Actual arguments and the arguments declared in function definition is known as Formal arguments. In call by value Formal arguments contains copy of actual arguments. In following example "a" and "b" are the Actual arguments which...

Programs to know differences between getch(), getche() and getchar()

Saturday, March 09, 2013 Basic C Programs

This post will explain major difference between getch(), getche() and getchar() functions. All of these functions get character input from user. Generally it is determined that getch() function is used to freeze console output. But it happens because whenever getch() function is called it waits for input of keyboard. Until the input is given getch() freezes the output screen. After getting input from user program continues. getche() also takes character input from keyboard and it also freezes output screen but the difference between...
