Question

Complete the function FindLastIndex() that takes one string parameter and one character parameter. The function returns the index of the last character in the string that is not equal to the character parameter. If no such character is found, the function returns -1.
Ex: If the input is tbbdn b, then the output is:
4
#include
using namespace std;
int FindLastIndex(string inputString, char x) {
/* Your code goes here */
}
int main() {
string inString;
char x;
int result;
cin >> inString;
cin >> x;
result = FindLastIndex(inString, x);
cout << result << endl;
return 0;
}

Answer 1

Using the codes in computational language in C++ it is possible to write a code that complete the function FindLastIndex() that takes one string parameter and one character parameter.

Writting the code:

#include <iostream>

using namespace std;

int FindLastIndex(string inputString, char x)

{

 // running a for loop that iterates the inputString from the last index and comes down to the 0th index. We are iterating from the last index because we want to find the last character such that it is not equal to x. So iterating the string from last makes more sense because we will find the value faster as compared to searching from the front to get that last value.

 for (int i = inputString.length() - 1; i >= 0; i--) {

   // if current character not equals the character x then return the index

   if (inputString[i] != x) {

     return i;

   }

 }

 // if the above loop didn't return an index, then all the characters are same in the string, hence return -1

 return -1;

}

int main()

{

 string inString;

 char x;

 int result;

 cin >> inString;

 cin >> x;

 result = FindLastIndex(inString, x);

 cout << result << endl;

 return 0;
