C Program To Print an Integer (Entered by the User)

In this post, we are going to Write a C Program To Print an Integer (Entered by the User).

The integer entered by the user is stored in a variable and printed on the screen.

So, Without further ado, let’s begin the tutorial.

C Program To Print an Integer

// C Program To Print an Integer
#include <stdio.h>
int main(){
    int num;
    // Display Message to Take Input
    printf("Enter an Integer: ");
    // Takes input from the User
    scanf("%d", &num);
    // Displays Output
    printf("The Entered Integer is: %d", num);
    return 0;
}

Output

Enter an Integer:18
The Entered Integer is: 18

How Does This Program Work ?

  int num;

In this program, we have declared an integer named num.

  scanf("%d", &num);

The input is taken by using scanf() function, the integer is stored in the num variable.

  printf("The Entered Integer is: %d", num);

Then, the value stored in the num variable is displayed on the screen using printf() function.

Some of the used terms are as follows:

#include <stdio.h> – In the first line we have used #include, it is a preprocessor command that tells the compiler to include the contents of the stdio.h(standard input and output) file in the program.

The stdio.h is a file which contains input and output functions like scanf() and printf() to take input and display output respectively.

Int main() – Here main() is the function name and int is the return type of this function. The Execution of any Programming written in C language begins with main() function.

Scanf() – Scanf() function is used to take input from the user. Here %d indicates that we are reading decimal/integer type.

printf() – printf() function is used to display and print the string under the quotation to the screen.
