print means to take out any image or document in reality

Answer 2

Short note on printf and scanf in C language:

(1) Printf:

= > It is used to display the output onto the output screen.

= > It is stored in <stdio.h>

= > It returns the number of bytes.

= > Syntax: printf("format string", arguments);


(2) Scanf:

= > It is used to take input from the user. 

= > It is stored in <stdio.h>

= > It does not return anything.

= > Syntax: Scanf("Format string", arguments);




Example:

#include<stdio.h>

void main()
{
int a,b,c;
printf("Enter two numbers");
scanf("%d%d", &a,&b);

c = a + b;
 
printf("Addition is: %d\n",c);
getch();
}
