我正在编写将采用整数数组的代码,然后可以将其转换为所需的基数,例如base-16.

出于某种原因,终端通过该程序并打印出来

"转换数="

这是我的代码:

#include <stdio.h>
#include <cs50.h>

int convertedNumber[64];
int base;
int digit = 0;

void getNumberAndBase(void) {
    int size;

    printf("How many numbers to be converted??\n");
    size = GetInt();

    int array[size];

    for (int i = 0; i < size; i++) {
        printf("Number to be converted?\n");
        array[i] = GetInt();
    }

    printf("Base?\n");

    do {
        base = GetInt();

        if (base < 2 || base > 16) {
            printf("Bad base - must be between 2 and 16. Try again!\n");
        }
    } while (base …

我正在编写一个程序来计算两次给定时间之间的经过时间.

由于某种原因,我收到错误:在我的main函数之前我的elapsedTime函数原型的预期标识符或'C'.

我试过在程序中移动它,如果在声明了t1和t2之后找到它,它就没有区别.有什么问题？

谢谢

#include <stdio.h>

struct time
{
  int seconds;
  int minutes;
  int hours;
};

struct elapsedTime(struct time t1, struct time t2);

int main(void)
{

    struct time t1, t2;

    printf("Enter start time: \n");
    printf("Enter hours, minutes and seconds respectively: ");
    scanf("%d:%d:%d", &t1.hours, &t1.minutes, &t1.seconds);

    printf("Enter stop time: \n");
    printf("Enter hours, minutes and seconds respectively: ");
    scanf("%d:%d:%d", &t2.hours, &t2.minutes, &t2.seconds);

    elapsedTime(t1, t2);

    printf("\nTIME DIFFERENCE: %d:%d:%d -> ", t1.hours, t1.minutes, t1.seconds);
    printf("%d:%d:%d ", t2.hours, t2.minutes, t2.seconds);
    printf("= %d:%d:%d\n", differ.hours, differ.minutes, differ.seconds); …
