C 变量值

int myNum = 15;  // myNum 是 15
myNum = 10;  // 现在 myNum 是 10

int myNum = 15;

int myOtherNum = 23;

// 将 myOtherNum (23) 的值赋给 myNum
myNum = myOtherNum;

// myNum 现在是 23，而不是 15
printf("%d", myNum);

// 创建一个变量并给它赋值 15
int myNum = 15;

// 声明一个变量但不给它赋值
int myOtherNum;

// 将 myNum 的值赋给 myOtherNum
myOtherNum = myNum;

// myOtherNum 现在的值是 15
printf("%d", myOtherNum);

int x = 5;
int y = 6;
int sum = x + y;
printf("%d", sum);
