Here you will get a C++ program to find highest or largest and lowest or smallest element of a matrix. Output Enter no. of rows and columns:3 3 Enter matrix: 3 5 9 15 6 0 12 4 7 Highest Element:15 Lowest Element:0
Here you will get C++ program to count number of words in string. First we initialize a counter variable to 1. Now iterate through string and count all the spaces, for each space increase the value of counter. Finally print the counter variable, it contains the number of words. Output Enter a string:how are you …
Here you will get C++ program to concatenate two string without using library function. Below program will read two strings from user and then concatenate them to form third string. Output Enter first string:Hello Enter second string:World The concatenated string is HelloWorld
Here you will get C++ program to reverse all the strings stored in an array. Output Enter 3 strings: how are you The list of orignal strings: how are you The list of changed strings: woh era uoy
Here you will get a C++ program to find the addition of two matrices. We can add two matrices only if they have similar dimensions. For example: Matrix A: 3 72 5 Matrix B: 5 61 4 The addition of A and B is: 8 133 9 Let us see the code for matrix addition …
Here you will get C++ program to check string is palindrome or not. A string is called palindrome if it is equal to its reverse. For example bob is string palindrome. Output Enter a string:saas The string is Palindrome
