Program to Print an Integer

Program to Print an Integer

#include <stdio.h>
int main()
{
    int number;

    // printf() dislpays the formatted output 
    printf("Enter an integer: ");  
    
    // scanf() reads the formatted input and stores them
    scanf("%d", &number);  
    
    // printf() displays the formatted output
    printf("You entered: %d", number);
    return 0;
}
Output
Enter a integer: 25 You entered: 25 In this program, an integer variable number is declared.
The printf() function displays Enter an integer: on the screen. Then, the scanf() function reads an integer data from the user and stores in variable number.
Finally, the value stored in the variable number is displayed on the screen using printf() function.
 

C "Hello, World!" Program


Program to Display "Hello, World!"

#include <stdio.h>
int main()
{
   // printf() displays the string inside quotation
   printf("Hello, World!");
   return 0;
}
Output
Hello, World! How "Hello, World!" program works?
  • The #include <stdio.h> is a preprocessor command. This command tells compiler to include the contents of stdio.h (standard input and output) file in the program.
    The stdio.h file contains functions such as scanf() and print() to take input and display output respectively.
    If you use printf() function without writing #include <stdio.h>, the program will not be compiled.
  • The execution of a C program starts from the main() function.
  • The printf() is a library function to send formatted output to the screen. In this program, the printf() displays Hello, World! text on the screen.
  • The return 0; statement is the "Exit status" of the program. In simple terms, program ends with this statement.
