Answer 3

See foody gyan
sizeof() operator is a flexible and versatile operator for computation of the bytes and the memory for ingesting the required values and return those values after computation. ...
Example ~
#include<stdio.h>
int main() {
int m = 80;
float n = 5.2;
printf("size of int becomes: %d\n", sizeof(m));
printf("size of float becomes %fu\n", sizeof(n));
printf("size of char becomes: %ld\n", sizeof(char));
return 0;
}
Hope this will clear✌️
