C++ Basic: Exercise-70 with Solution

Write a C++ program to replace all the lower-case letters in a given string with the corresponding capital letters.

Visual Presentation:

Sample Solution:

C++ Code :

#include <iostream> // Including input-output stream header file
#include <algorithm> // Including algorithm header for transform function
using namespace std; // Using the standard namespace

int main() {
    string text; // Declaring a string variable named 'text' to store user input

    getline(cin, text); // Getting a line of text input from the user

    // Using transform function to convert each character of the string to uppercase
    transform(text.begin(), text.end(), text.begin(), ::toupper);

    // Displaying the converted string in uppercase
    cout << text << endl;

    return 0; // Indicating successful completion of the program
}

Sample Output:

Sample Input 
the quick brown fox jumps over the lazy dog. 
sample Output
THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG.

C++ Code Editor:

Previous: Write a C++ program to read an integer n and prints the factorial of n, assume that n ≤ 10.
Next: Write a C++ program which reads a sequence of integers and prints mode values of the sequence. The number of integers is greater than or equals to 1 and less than or equals to 100.
