Could someone please help me find out what's going on? I'm using C language to read a csv file into an array. There's a syntax problem. I don't know what's wrong?

#include

# define MAX_LINE 1024

int main(){

FILE *fp=NULL;

fp = fopen("test.csv","r");

char a[1024];

char *p;

char *q;

int len;

< p> int i = 0;

int j = 0;

fseek(fp,0L,0);

while(fgets(a,MAX_LINE, fp) != NULL)

{

p = &a[0];

q = &a[0];

/ /printf("%s\n", a);

while(*p!='\0'){

while(*p !=','&&* p!='\0'&& *p != '\r' && *p != '\n'){?

p++;

}

< p> char *part = (char *)malloc(100 * sizeof(char));

int length = p - q;

if (length>0){

printf("%d",length);

memcpy(part, q, length);

part[length]= '\0';

printf("%s\n",part);

}

p = p+1;

q = p;< /p>

}

return 0;

}
