#include<bits/stdc++.h>
using namespace std;
int main(){
char a[100];
cin>>a;
for(int i=strlen(a);i>=0;i--){
cout<<a[i];
}
return 0;
}

for(int i=strlen(a);i>=0;i--){

应为

for(int i=strlen(a)-1;i>=0;i--){

@chuxuanzhe 谢谢

@wanyuanshenma 显然 a[strlen(a)] 是一个空的值吧，循环改成for(int i=strlen(a)-1;i>=0;i--){

我用的拼接 float a,s,d,f,g; cin>>a; s=int(a10)/1000; d=int(a10)/100%10; f=int(a10)/10%10; g=int(a10)%10; cout<<g<<"."<<f<<d<<s;

@wanyuanshenma 你在循环时应该是 (i=strlen(a)-1)
还有，我建议你输入用

cin.getline(a,100);

试试这个：

#include <bits/stdc++.h>
using namespace std;

int main() {
    string s;
    cin >>s;
    for (int i = s.size()-1; i >= 0; i--) {
        cout << s[i];
    }
    system("pause");
    return 0;
}
