    return 0;

}

Program3: Data types.c

#include <stdio.h>

int main(){

    int i = 5; // It stores an integer.

    float f = 4.5; // It stores a decimal number.

    char c = 'A'; // It stores character.

    printf("%d", i); // format specifier for Integer

    printf("%f", f); // Format specifier for float

    printf("%c", c); // format specifier for charachter

    scanf("%d", &a); /* & opreator to store it's value or address.

     What is address you will learn about this in pointers but for this

     time you should remember that it is
