Thread: Reversing string

Hello,

I have a string say,

"My name is John"

I want to reverse it like,

"yM eman si nhoJ"

I wrote a program for it which compiles but doesn't give answer. Can anyone tell me what is the problem in my program. Thanks a lot for all your help

Code:

void reverse(char *str){
     char * temp = str;
     char substr[10];
     int i = 0, j = 0, k = 0;
     while(*temp != '\0'){
                 if(*temp != ' '){
                          substr[i] = *temp;
                          i++;
                          }
                 else{
                      if(i>0){
                               for(j=i; j>0;i--){
                                       *str++ = substr[j];
                                       }
                                       *str++ = ' ';
                                       k = 1;
                  }
                  }
                  if(k = 1){
                      i = 0;
                       j = 0;
                       k = 0;
                      }
             
             }
             *str = '\0';
     }

int main(){
    char * text = "My name is John";
    cout<<text<<endl;    
    reverse(text);
    cout<<text;
    system("PAUSE");
    }
