A for loop is a common way to iterate through a string in C++. It allows you to access each character in sequence.ExampleOpen Compiler #include <iostream> #include <string> int main() { std::string str = "TutorialsPoint"; for (size_t i = 0; i < str.length(); ++i) { std::...

We can also use the foreach loop in an associative array to loop through the key and value of the array. An associative array is a type of array that contains a key and value pair for each item of the array.Using the foreach loop, we can obtain the key and value of the array ...

This code shows how to use rangedfor loops to iterate through an array and a vector: C++ // range-based-for.cpp // compile by using: cl /EHsc /nologo /W4 #include <iostream> #include <vector> using namespace std; int main() ...
There is also a "for-eachloop" (also known as ranged-based for loop), which is used exclusively to loop through elements in anarray(or otherdata structures): Syntax for(type variableName:arrayName) { // code block to be executed
The inner loop iterates through all the columns for every single row iteration by the outer loop. After both the loops terminate, the sum array will store the addition of matrix1 and matrix2. As mentioned in the code comments, we then print the sum array (representing the sums), using...
