C 程序 查找int，float，double和char的大小

#include<stdio.h>
int main()
{
    printf("Size of char: %ld byte\n",sizeof(char));
    printf("Size of int: %ld bytes\n",sizeof(int));
    printf("Size of float: %ld bytes\n",sizeof(float));
    printf("Size of double: %ld bytes", sizeof(double));
    return 0;
}

Size of char: 1 byte
Size of int: 4 bytes
Size of float: 4 bytes
Size of double: 8 bytes
