Aips: Can u rewrite the following question.

TusharDes: sure

TusharDes: write a program in c++ to accept a string and find the length of the string without using library function

Aips: #include<iostream>
#include<stdio.h>

using namespace std;

int main()
{
char a[30];
int i;
cout<<"Enter a string:";
gets(a);

for(i=0;a[i]!='\0';++i);

cout<<"\nLength of the string '"<<a<<"' is "<<i;

return 0;
}

Aips: May this help you

TusharDes: what is the meaning of for(i=0;a[i]!='\0')

Aips: In this case "for(int i = 0; a[i]; i++)", your loop keeps its execution until one of its elements are a null element. Always when you see this expression, it is always the same meaning that is checking out whether element is or not null, in order to stop the loop.

Aips: However that loop has a undefined behavior, because if the index i will arrive at maximum array's size. It's likely you are going to receive a run-time error of that type:

Error for being out of range array size or you are trying to access a null space of memory.

I hope that my answer, it is suitable for your problem..

TusharDes: thank you
