刚开始学C，写了几行代码，报错了,用的是VS2015，报的错是c2040, getstra”: “char *()” differs in levels of indirection from “int ()” ，看了好久不清楚啥问题，请各位帮看看，谢谢
#include <stdlib.h>
int main() {
char *ssa = getstra();
printf("%d\n", *ssa);
free(ssa);
system("pause");
return 0;
}
char *getstra() {
char *bufa = malloc(sizeof(char) * 100);
strcpy_s(bufa,"abcdefg",10);
return bufa;
}

本人来给个代码
#include "stdafx.h"
#include <stdlib.h>
#include <string.h>
char *getstra(){
char *bufa=(char*)malloc(sizeof(char)*100);
strcpy(bufa,"abcdefg");
return bufa;
}
int main()
{
char *ssa=getstra();
printf("%d\n",*ssa);
free(ssa);
system("pause");
return 0;
}

strcpy_s参数顺序反了
需要在main前加上char *getstra();声明
需要在main前加上char *getstra();声明
#include <stdlib.h>
char *getstra();
int main() {
char *ssa = getstra();
printf("%d\n", *ssa);
free(ssa);
system("pause");
return 0;
}
char *getstra() {
char *bufa = (char*)malloc(sizeof(char) * 100);
strcpy_s(bufa, 100, "abcdefg");
return bufa;
}

#include <stdlib.h>
char *getstra(); //首先这里要声明，这就是错误显示的原因
int main() {
char *ssa = getstra();
printf("%d\n", *ssa);
free(ssa);
system("pause");
return 0;
}
char *getstra() {
char *bufa = malloc(sizeof(char) * 100);
strcpy_s(bufa,"abcdefg",10);
//strcpy_s(bufa,10,"abcdefg"); //函数应该是这样
return bufa;
}
