Question

所以我正在调用一个简单的方法，从头文件到主C文件，它不起作用。任何线索？

Main

#include "header.h"

int main() {
    int a = 2;
    int b = 5;
    int numArray[2] = {a, b};
    displayNumbers(numArray, 2);
    doubleIt(a);
    doubleIt(b);
    displayNumbers(numArray, 2);
    return(0);
}

Header

int doubleIt(int x) {
    return 2 * x;
}

void displayNumbers(int x[], int numSize) {
    int i;
    for (i = 0; i < numSize - 1; i++) {
        printf("%d, ", x[i]));
    printf("%d", x[numSize - 1]);
    printf("\n");
}

doubleIt方法不起作用。

如果我正确理解了您的问题，您希望将数组加倍并打印值，如果是<div class="div-roomcart" id="divOAK1AKL"> <div class="div-roomcart-hotel"> <div class="div-roomcart-hotelname">Eden Park Bed And Breakfast</div> <div class="div-roomcart-roomtype">Single Standard</div> </div> <div class="div-roomcart-room"> <div class="div-roomcart-roomprice">14058.26</div> <div class="div-roomcart-roomaction"> <input type="submit" id="submit" value="Remove" class="btnbook" onclick="removeroom('divOAK1AKL')"> </div> </div>和a = 2，那么您希望加倍到b = 5和{{ 1}}。在代码中修改这些行，如下所示;

a = 4

希望这有帮助。

从标头调用方法不起作用？ [C]
