错误:
str3.c:在函数'main'中: str3.c:15:14:错误:解除引用不完整类型'struct st'的指针 的scanf("%S",&安培;对 - >名称); ^ str3.c:在函数'call'中: str3.c:25:22:错误:'sizeof'无效应用于不完整类型'struct st' return malloc(sizeof(struct st));
答案 0 :(得分:0)
1)您必须添加括号scanf("%d", &p->rollno)
- > scanf("%d", &(p->rollno))
2)但是你在阅读字符串
时不需要括号输出:
enter roll no.
1
enter name
stackoverflow
enter marks
3.14
1 stackoverflow 3.140000
代码:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
struct st
{
int rollno;
char name[256];
float marks;
};
struct st *call(void)
{
return malloc(sizeof(struct st));
}
int main()
{
struct st *p;
p = call();
printf("enter roll no.\n");
scanf("%d", &(p->rollno));
printf("enter name\n");
scanf("%s", p->name);
printf("enter marks\n");
scanf("%f", &(p->marks));
printf("%d %s %f\n", p->rollno, p->name, p->marks);
}
