小编ldd*_*345的帖子

我不断收到一条错误消息“警告：指针和整数之间的比较”。我尝试使用 char* 但仍然遇到相同的错误。我想计算字符串中出现的逗号数量，并将出现的次数放入计数器中。

int main(int argc, char *argv[]) {

    /*FILE *fp;
    fp = fopen("csvTest.csv","r");
    if(!fp){
        printf("File did not open");
    }*/


    //char buff[BUFFER_SIZE];
    char buff[100] = "1000,cap_sys_admin,cap_net_raw,cap_setpcap";    

    /*fgets(buff, 100, fp);
    printf("The string length is: %lu\n", strlen(buff));
    int sl = strlen(buff);*/

    int count = 0;
    int i;
    for(i=0;buff[i] != 0; i++){
        count += (buff[i] == ",");
    }
    printf("The number of commas: %d\n", count);




    char *tokptr = strtok(buff,",");
    char *csvArray[sl];

    i = 0;
    while(tokptr != NULL){
          csvArray[i++] = tokptr;
          tokptr …
