Program In C To Calculate Size Of Different Data Types


#include <stdio.h>
#include <conio.h>

int main(){

int *a;
printf("\nSIZE OF DIFFERENT DATA TYPES\n");
printf("\n------------------------------");
printf("\n\tBASIC");
printf("\n------------------------------");
printf("\nCHARACTER \t: %d byte(s)",sizeof(char));
printf("\nSHORT \t\t: %d byte(s)",sizeof(short));
printf("\nINTEGER \t: %d byte(s)",sizeof(int));
printf("\nLONG \t\t: %d byte(s)",sizeof(long));
printf("\nFLOAT \t\t: %d byte(s)",sizeof(float));
printf("\nDOUBLE \t\t: %d byte(s)",sizeof(double));
printf("\nLONG DOUBLE \t: %d byte(s)",sizeof(long double));
printf("\nLONG LONG \t: %d byte(s)",sizeof(long));
printf("\nPOINTER (any) \t: %d byte(s)",sizeof(*a));
printf("\nARRAY \t\t: sizeOfDataType * sizeOfArray [eg. int a[10]=%d byte(s)]",sizeof(int)*10);
printf("\n------------------------------");

return 0;
}

  1. hey, this is a good program.
    sometimes we are asked to calculate the size of data-types without using sizeof operator. In that case we can use pointers to find the size.
