strtok函数的使用

int Split(char* src,const char* delimiters,char* output[]){
	int output_index = 0;
	char* p = strtok(src,delimiters);
	while (p != NULL){
		//切分结果放在数组中
		output[output_index] = p;
		output_index++;
		p = strtok(NULL, delimiters);
	}
	return output_index;
}
int main(){
	char str[] = "aaa,bbb,ccc,ddd";
	char* output[100] = { 0 };
	int n = Split(str, ",", output);
	for (int i = 0; i < n; ++i){
		printf("%s\n", output[i]);
	}
	system("pause");
	return 0;
}

也可以这么用

int main(){
	char str1[] = "sing,dance-rap+basketball";
	puts(strtok(str1, ",-+"));
	puts(strtok(NULL, ",-+"));
	puts(strtok(NULL, ",-+"));
	puts(strtok(NULL, ",-+"));

	system("pause");
	return 0;
}
