objective-c - 我正在尝试从目标 c 中的控制台读取整数值

Question

当我读取第一个值时，它不会取值并继续循环。当我按“esc”和“enter”时，它将读取第二个数字但不取第二个数字，程序执行完成..

int main (int argc, const char * argv[])
{

    // insert code here...
    int firstNumber = 0,secondNumber = 0,result = 0;

    printf("\nEnter first number");
    scanf("%d", &firstNumber);

    printf("\nEnter second number");
    scanf("%d", &secondNumber);

    result = firstNumber+secondNumber;

    printf("\nResult is %d", result);

    return 0;
}

您的代码有效，请再次检查！您可以稍微修改它以在新行中输入数字

    int first = 0, second = 0, result = 0;
    printf("Enter the first number: \n");
    scanf("%d",&first);
    printf("Enter the second number: \n");
    scanf("%d",&second);
    result = first + second;
    printf("Result is: %d \n", result);
    cout << "\nEnd";
    return 0;
