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; }My thought is your code is working far too hard. It looks like each string is scanned by your code 7 times over and over.
If this was mine this could be replaced with 7 calls to std:replace as noted in method 2 at https://www.techiedelight.com/replace-occurrences-character-string-cpp/
Neither for or while is required here.
