how to reverse words in a sentence without helper methods in c++?

Question

I need to read string of characters (with spaces) and reverse it. First i read a string of characters from console. ``` char array[100]; for(int i = 0; i < sizeof(array); i++) array[i] = '0'; for(int i = 0; i < sizeof(array); i++) cout<<array[i]<<" "; cout<<"

enter your string: "; cin.getline(array, 100); cout<<"
"; for(int i = 0; i < sizeof(array); i++) cout<<array[i]<<" "; ``` Then i create and fill indexes array. (to remember space spots) ``` cout<<"

indexes: "; int indexes[20]; for(int i = 0; i < 20; i++) { indexes[i] = 0; } // filling the indexes array int j = 0; for(int i = 0; i < sizeof(array); i++) { if(array[i] == '0') break; if(array[i] == ' ') indexes[j++] = i; } // validating indexes array for(int i = 0; i < sizeof(indexes); i++) { //if(indexes[i] == 0) break; cout<<indexes[i]<<" "; } ``` Here is the begining of my (i guess not smart) algorythm. I want to reverse first word. Seems like this chunk never executes. Why? ``` // first word int j1 = indexes[0]-1; for(int…

Accepted Answer

Your intuition is right: the loop isn't being executed. The problem is in the line:

```
for(int i = 0; i > indexes[0]; i++)
```

The comparison should be `i < indexes[0]`.
