如何使用结构的指针变量的typedef指向相同的结构varible

Question

#include<stdio.h>
//This program is about structure and there pointer
//
typedef struct{
    int i;
    char c;
}str1,*strptr;

str1 str[5];
strptr *ptr;

int main(){
    ptr = &str;// This is shown as incompatible type assignment **warning**
    ptr->i=35; // **error**: request for member 'i' in something  
               //not a structure or union

    ptr->c='d';//**error**: request for member 'c' in 
                // something not a structure or union
    printf("My structure values are %d %c\n",str[0].i,str[0].c);

return 0;
}

当我运行这个程序时,会出现一个警告和两个错误.请阅读注释行以获取警告和错误.

我错过了什么？

Answer 1

在您的代码中,strptr已经是指针类型.你需要改变

strptr *ptr;

至

strptr ptr;
