I can not understand why my sources get compile error , I have written 2 for this task : 

// 1st one - compile error
#include <iostream>
#include <string>
#include <algorithm>
#define FOR(i,n) for(int i=0;i<n;i++)
using namespace std;

string a,b,tmp,code;

int main() {
    cin>>a;
    b = a;
    while(cin >> tmp) {
        code+=tmp;
        code+=" ";
    }    
    cout << code;
    FOR(i,a.size()) b[i] = toupper(a[i]);
    for(int i=0;i<code.size();i++) {
        if(code[i] == ' ') cout << " ";
        else if(code[i]>='a' && code[i]<='z')cout << a[code[i]-'a'];   
        else cout << b[code[i]-'A'];
    }     
    cout << endl;
    return 0;
}

// 2nd one - compile error
#include <stdio.h>
#include <string.h>
using namespace std;
char a[26],b[26];
char c[81];

int main() {
    gets(a);
    gets(c);
    for(int i=0;i<26;i++) b[i] = a[i] - ('a'-'A');
    for(int i=0;i<strlen(c);i++) {
        if(c[i] == ' ') printf(" ");
        else if(c[i] >= 'a' && c[i] <= 'z') printf("%c",a[c[i]-'a']);
        else printf("%c",b[c[i]-'A']);
    }
    return 0;    
}    

I compile them as a "C++"
So what is the problem :( Please help

      • then you can use g++ to submit c++ code and gcc to submit c code (105) hawk 2004-12-04 02:12:20
    • also java here is jdk1.5,welcome use it (0) hawk 2004-12-04 02:12:52
