If I comment the function call (cc(a,loc,ch,&num);) it will compile. 如果我注释函数调用(cc(a,loc,ch,&num);),它将进行编译。 Any suggestions? 有什么建议么? This is my first programming course and Ive been beating my head over this for far too long. 这是我的第一门编程课程,而我为此一直都在努力。
Output with function call commented out: 函数调用已注释掉的输出:

You have an extra ";" 您还有一个额外的“;” in cc
function definition: 在cc
函数定义中:
void cc(char a[][NC], int loc[NCC][2], char ch, int *num); {
int i,j,k,loc[NCC][2],num;
char ch, arr[NR][NC];
k0;
You have a semicolon after your function declaration here: 您在此处进行函数声明后有分号:
void cc(char a[][NC], int loc[NCC][2], char ch, int *num); {
Which is causing it to be a declaration, and not a definition of the function. 这导致它成为函数的声明,而不是函数的定义。 I believe that removing that semicolon should make the linker error go away, but frankly it's hard to tell; 我相信删除该分号应该可以使链接程序错误消失,但是坦率地说,这很难说。 you'll have an easier time of it if you keep your code properly formatted and indented. 如果您对代码进行适当的格式化和缩排,则可以轻松地完成工作。
