How it shows "int : 4".... there is nothing mentioned like "4"...

Question

#include <stdio.h>

int main() {
printf("int: %ld \n", sizeof(int));
printf("float: %ld \n", sizeof(float));
printf("double: %ld \n", sizeof(double));
printf("char: %ld \n", sizeof(char));

return 0;
}

Answer 1

The sizeof method returns the amount of memory allocated to a data type or an expression. The value for the same data type is different for 32 - bit and 64 - bit machines. The memory allocated to different data types in C is given below,

int - 4 bytes
float - 4 bytes
double - 8 bytes
char - 1 byte

Answer 2

It means in C Program,,, for each integer needs 4 bytes....
