我有一个打开.txt的函数,使用fscanf读取格式如下的数字:

532
2
-234
32

当我使用GCC编译时,它成功地执行了此操作,但是我无法在Xcode中打开文件,为什么？相关代码是:

int main (void){
    FILE *infile = NULL;  //input file buffer
    int int_array[100];   //an integer array 100 entries long
    char infilename[256];  //an extra large char array 
        //this entire while loop was provided as part of the assignment, 
        //we weren't supposed to change it. I've finished this assignment, 
        //but now I want to know how to use my Xcode debugger
    while(infile == NULL) {
        printf("Input filename:");     //user prompt
        scanf("%s",infilename);        //store user input in large char array …
