C++ 基本数据类型 int, double

• int占4个字节，double占8个字节
• 数组地址连续

#include <stdio.h>
#include <iostream>

using namespace std;

int main()
{
    int i[10] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9};
    double d[10] = {1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2};
    printf("size of i[0] is %d, size of d[0] is %d \n", sizeof(i[0]), sizeof(d[0]));

    for (int k = 0; k < 10; k++) {
        printf("i[%d] value is %d, address is: %p \n", k, i[k], &i[k]);
    }

    for (int k = 0; k < 10; k++) {
        printf("d[%d] value is %f, address is: %p \n", k, d[k], &d[k]);
    }

    return 0;
}
