@codecrawler : Why are you checking for ‘\0’ . The new line character is ‘\n’ .

Set len = 0 “inside” the first for-loop.

i think he is finding length of string in this case(so increasing value till a null character is met)
also using namespace std is missing

5

just find the length of your string using strlen() function

thnx…i will try…let me know…i should use this code

while(a[len]!=’\0’)
{
len++
}

for calculating string length or strlen fn. and why?

@codecrawler…use of above method is good…use it…strlen does the same thing(SO)…u save time of calling a fxn…though it is not a lot…but an optimization is an optimization…:stuck_out_tongue:

you can reduce your code and stress…
For strlen hope yo know the syntax…:slight_smile:
Happy coding…:slight_smile:
