There is no way to convert ostream and int to the same common type, and that's what the compiler told you (in a slightly odd way, compare to current messages from clang "incompatible operand types ('int' and 'basic_ostream<char, std::__1::char_traits<char> >')") ...

当访问函数变体时出现"Invalid conversion"错误是因为类型转换不正确,导致编译器无法识别或处理函数调用的参数类型。以下是可能导致此错误的几种常见情况及其解决方案: 1. 参数类型不匹...
if((strcmp(u->id,id[20])==0)//比对用户名 这里有问题，改成 if((strcmp(u->id,id)==0)//比对用户名 这样才是两个字符串的比较 但是你这里u没有初始化，他是一个指针，系统是不自动给他分配空间的 id 也没有被初始化
invalid conversion from 'int' to '在C语言中是什么意思 简介 在调用函数的时候传递的是int类型的数据，但那个函数定义的参数类型不是int（比如是结构或者指针或者数组）。#include#include"stdlib.h"int main(){int i,j,k;int *q;q=(int*)malloc(sizeof(int));scanf("%d %d %d",&i,&j,&k);if(i...
