hey , if i wanna write this code by " while" loop , what the steps to do that ??

#include<iostream.h>
char *TESTmarks(char *t){

    char marks [] = {'.',';',':','!',',','?'};
    char *newm=new char [strlen(t)];

    for( int i = 0;i<strlen(t);i++)
        {

        for(int k = 0;k<=7 ;k++)
            {
            if(t[i] == marks[k])
                t[i] = ' ';
            }
        }  
       return t;
    }

main()
{
    char t[50];
    cin>>t;
    cout<<TESTmarks(t);
}

The while loop will need the same parts that are part of the for loop. Counter, limit,incrementing. In a while loop the limit is included in the statement. The counter is initialized before the statement and the incrementing is done inside the block. As an example:

    //counter
    int i = 0;
    //limit
    while( i<strlen(t))
    {
        for(int k = 0;k<=7 ;k++)
        {
            if(t[i] == marks[k])
                t[i] = ' ';
        }
        //incrementing
        ++i;
    }  
   return t;
}
