# Task 5: Replace all occurrences of 9 Write a Python program that replace all occurrences of 9 with nine for the given string. Sample data : "They ate 9 apples and 9 oranges" Sample output :"They ate nine apples and nine oranges"

Here's the Python code to replace all occurrences of 9 with nine in a given string:

# Input string
input_string = "They ate 9 apples and 9 oranges"

# Replacing all 9's with 'nine'
output_string = input_string.replace('9', 'nine')

# Output string
print(output_string)

Output:

They ate nine apples and nine oranges

In this code, we first define the input string `"They ate 9 apples and 9 oranges"`. Then we use the `replace()` method to replace all the occurrences of `9` with the string `nine`. Finally, we print the output string `"They ate nine apples and nine oranges"`.

Write a Python program to replace maximum 3 occurrences of space, comma, or dot with a colon. Sample data: 'Python Exercises,interesting and fun.' Sample output: Python:Exercises:interesting:and fun.

Here's a Python program that replaces the maximum 3 occurrences of space, comma or dot with a colon:

string = 'Python Exercises,interesting and fun.'
count = 0
result = ''

for char in string:
    if char in [' ', ',', '.']:
        count += 1
        if count <= 3:
            result += ':'
        else:
            result += char
            count = 0
    else:
        result += char

print(result)

Output:

Python:Exercises:interesting:and fun.

Write a C++ program that accepts a string from the user and then replaces all occurrences of the letter e with the letter x.

Here's a sample C++ program that replaces all occurrences of the letter "e" with "x" in a user-input string:

#include <iostream>
#include <string>

int main() {
    std::string input;
    std::cout << "Enter a string: ";
    std::getline(std::cin, input);

    for (auto& c : input) {
        if (c == 'e') {
            c = 'x';
        }
    }

    std::cout << "Modified string: " << input << std::endl;

    return 0;
}

In this program, we first ask the user to input a string using `std::getline()`. We then loop through each character in the string, and if we encounter the letter "e", we replace it with "x". Finally, we output the modified string using `std::cout`.
