如果语句不工作？ [英] If statements not working?

问题描述

我在编程小白。我只是想问问有什么不妥以下code：

I am a noob at programming. I just wanted to ask what is wrong with the following code:

scanf("%i", &battlechoice);

printf("BCHOICE WAS:%i\n", battlechoice);

if (battlechoice=4) //fleeing
{
    fleechance=rand() % 100;
    if (fleechance <= 49)
    {
        printf("You attempt to flee...\n");
        sleep(2000);
        printf("Oh dear! You failed to flee! Gamover!\n");
        printf("Thank you for playing! -Anthony\n");
        sleep(7000);
        exit(0);
    } 
    else
    {
        printf("You succeeded in fleeing! You will be returned to town\nshortly...\n\n\n\n\n");
        sleep(3000);
        break;
    }
}        //end fleeing

else if (battlechoice=1) //attacking
{
    //player damage gen
    printf("You commence the attack...\n");
    sleep(750);
    damagemax = rand() % lvl * 1.4;

    damageoutcome = damagemax + damagemin;
}

正在发生的事情是，它是做双方的if语句，尽管它们都具有不同的条件？哪里不对？先谢谢了。

What is happening is that it is doing both of the if statements, even though they both have different conditions? What is wrong? Thanks in advance.

推荐答案

你混淆赋值运算符 = 与等于运算符 == 。而不是这样写：

You're confusing the assignment operator = with the equals operator ==. Write this instead:

if (battlechoice == 4)

等。

某些C程序员使用尤达条件句，以避免无意中在这些情况下使用分配：

Some C programmers use "Yoda conditionals" to avoid accidentally using assignment in these cases:

if (4 == battlechoice)

例如，这将不能编译，捕捉错误：

For example this won't compile, catching the mistake:

if (4 = battlechoice)
