C语言输入1~12 数字输出1月到12月的英文

答案：可以使用 switch 语句实现，代码如下：

#include <stdio.h>

int main() {
    int month;
    printf("请输入1~12之间的数字：");
    scanf("%d", &month);
    switch (month) {
        case 1:
            printf("January\n");
            break;
        case 2:
            printf("February\n");
            break;
        case 3:
            printf("March\n");
            break;
        case 4:
            printf("April\n");
            break;
        case 5:
            printf("May\n");
            break;
        case 6:
            printf("June\n");
            break;
        case 7:
            printf("July\n");
            break;
        case 8:
            printf("August\n");
            break;
        case 9:
            printf("September\n");
            break;
        case 10:
            printf("October\n");
            break;
        case 11:
            printf("November\n");
            break;
        case 12:
            printf("December\n");
            break;
        default:
            printf("输入错误，请输入1~12之间的数字。\n");
            break;
    }
    return 0;
}
