Explanation / Answer

Here is your code: -

#include<iostream>
#include<cstring>

using namespace std;

int main() {
   cout<<"Enter a line of text:";
   char str[80];
   cin.get(str, 80); // getting whole line and saving it in str array
   cout<<"Enter a character to replace:";
   char c;
   cin>>c;
   cout<<"Enter a character to replace "<<c<<" with:";
   char r;
   cin>>r;
  
   int len = strlen(str); // getting length of string
   int count = 0;
   for(int i = 0; i<len;i++) {
       if(str[i] == c) { // checking if character matches in string then increase the count and replace it with the other character
           count++;
           str[i] = r;
       }
   }
  
   cout<<endl;
   cout<<"Count of "<<c<<" :"<<count<<endl;// printing count
   cout<<"New Line :";
   for(int i = 0; i<len;i++) {//printing new line
       cout<<str[i];
   }
   return 0;
}
