🚀 Programming Example
sizeof() operator, Returns the size of a variable.
Learn this program step-by-step with algorithm, source code, output and detailed explanation.
#include <stdio.h>
int main()
{
int a, e[10];
float b;
double c;
char d;
printf("Size of int=%lu bytes\n",sizeof(a));
printf("Size of float=%lu bytes\n",sizeof(b));
printf("Size of double=%lu bytes\n",sizeof(c));
printf("Size of char=%lu byte\n",sizeof(d));
printf("Size of integer type array having 10 elements = %lu bytes\n", sizeof(e));
return 0;
}
Size of int=4 bytes
Size of float=4 bytes
Size of double=8 bytes
Size of char=1 byte
Size of integer type array having 10 elements = 40 bytes

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
