如何使用使用C的switch语句查找-14至14的数字平方

Question

使用switch语句或while循环，如何找到从-14到14的数字平方。我对应该如何开始感到困惑。

Answer 1

只需从-14上升到14：

for(int i = -14; i <= 14; i++)
{
    printf("%d squared is %d\n", i, i * i);
}

while循环：

int i = -14;

while(i <= 14)
{
    printf("%d squared is %d\n", i, i * i);
    i++;
}

switch：

switch(0)
{
    int i;
    default:
    i = -14;

    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    printf("%d squared is %d\n", i, i * i);
    i++;
    break;
}
