Scanf In C

scanf

printf has now become our friend. printf is a “function” i.e. a statement that prints some text
on the screen. Similarly, scanf is also a “function” used to take input from the keyboard.
scanf statement looks a lot like printf statement.



Syntax:
Note %d << If you've created variable integer use %d, if character use %c, if float use %f, Note the "&" ampersand operator use to point variables address

scanf("%d", &variablename); 

Example#1:

/* Ask user age and display message */

#include
int main()
{
int age = 0;
printf("Enter your age : "); /* Asking user age */
scanf("%d" , &age); /* taking input from user. Note the & operator */
printf("\n You are %d years old", age);
return 0;
}
