Given a string, an integer position, and a character, all on separate lines, find the character of the string in that position and replace it with the character read. Then, output the result.

Ex: If the input is:

warn

0

e

the output is:

earn

Note: Using a pre-defined string function, the solution can be just one line of code.​

Answer:

The program in Python is as follows:

myStr = input()

pos = int(input())

chrr = input()

myList=[]

myList[:0]=myStr

myList[pos] = chrr

myStr =""

for i in myList:

   myStr+=i

print(myStr)

Explanation:

This gets input for the string

myStr = input()

This gets input for the character position

pos = int(input())

This gets input for the incoming character

chrr = input()

Create an empty list

myList=[]

Convert the string to a list

myList[:0]=myStr

Replace the character

myList[pos] = chrr

Empty the string

myStr =""

Get the new string

for i in myList:

   myStr+=i

Print the new string

print(myStr)

Following are the C++ program to replace the first index value of the string.

Program Explanation:

  • Defining header file.
  • Defining the main method.
  • Inside the main method three variable "Sval, Spos, Subchar" is declared in which "string, int, and char".
  • After input variable value a string variable is declared with the at (method), which replaces the first index value with the character value.
  • After replacing the first index value that is "0" use the prints method that prints its value.

Program:

#include <iostream>//header file

#include <string>//header file

using namespace std;

int main() //main method

{

 string Sval;//defining string variable

 int Spos;//defining integer variable

 char Subchar;//defining char variable

 cin>>Sval>>Spos>> Schar;//input value

 Sval.at(Spos)  =  Subchar; //using string variable that replaces the first index value with the character value

 cout << Sval << endl;//printing the replaced value

 return 0;

}

Output:
