problem – How to write a C program to print an integer?

In this tutorial, we discuss the simple concept of C program to print an integer

input-output

In this article, we are going to learn how to write a C program to print an integer

The following shows two different ways to How to write a C program to print an integer and there is an example given to each

The first Example is done by declared and initialized the variable

The second Example is done through the user entered the value of the variables

C code to print an integer

Program 1

//C program to print an integer
#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num;//variable declaration
    num=67; //initialization
    printf("You declared: %d\n",num);
    getch();
    return 0;
}

When the above code is executed it produces the following output

You declared: 67;

In this program,

Integer variable num is declared
Integer variable num is initialized
Then, the program has Displayed the output (value of variable num ) using printf() function

C code print an integer(Entered by user)

Program 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int num;//variable declaration
   
    printf("Enter the integer to display: ");
    scanf("%d",&num);
    printf("You entered: %d \n",num);
    getch();
    return 0;
}

When the above code is executed it produces the following output

Enter the integer to display: 125
You ebtered: 125

Method

The program requires input from the user
Then the user enters the input value
The program will read the input using scanf() and stores in the num variable
Then, the program Display the value which is in variable num using printf() function
