It's a scope problem: When you declare a variable inside a 'for' loop or a function, it only will be available until the loop/function ends. For example in your for loop: for(int i=0;text[i]!='\0';i++) as 'i' is declared and inicialized at the begining of the for loop, as soon as the loop finishes, it'll be destroyed and you won't be able to access to it anymore.

  • Yeah. I altered that. you are right.Thank you so much for looking into and helping me find my error. – Srushti Kanade Apr 27 '20 at 8:03

The variables that you create in the for loops only exist within that for loop. You can use the result of a certain iteration of a for loop by eg: including an if function within the for loop to pick up what you are after .

  • Yeah. I altered that. you are right, it does get confusing having these variables as I constantly have to look up what was assigned to which counter. I assigned those counters before the loop and corrected minor errors in bracket placement of loops and it worked. Thank you so much for looking into and helping me find my error. – Srushti Kanade Apr 27 '20 at 8:03
