Hello, World!
```c
include
int main() {
printf("Hello, World!\n");
return 0;
}
```
计算两个整数的和
```c
include
int main() {
int num1, num2, sum;
num1 = 5;
num2 = 3;
sum = num1 + num2;
printf("两数之和为: %d\n", sum);
return 0;
}
```
判断一个数是否为偶数
```c
include
int main() {
int num;
num = 8;
if (num % 2 == 0) {
printf("%d是偶数\n", num);
} else {
printf("%d是奇数\n", num);
}
return 0;
}
```
猜数字游戏
```c
include include include int main() { int num, guess; srand(time(0)); num = rand() % 100 + 1; do { printf("请输入一个数字(1-100):"); scanf("%d", &guess); if (guess > num) { printf("太大了!\n"); } else if (guess < num) { printf("太小了!\n"); } } while (guess != num); printf("猜对了!\n"); return 0; } ``` 输出九九乘法表的左上半角 ```c include int main() { int k, i, j; for (i = 1; i <= 9; i++) { for (j = 1; j <= i; j++) { printf("%d*%d=%d\t", j, i, i * j); } printf("\n"); } return 0; } ``` 这些实例涵盖了C语言的基本输入输出、条件判断、循环等基本概念。希望这些示例对你有所帮助。
