You can use a “ for loop ,” “ while loop ,” and for “ each loop .”. Here we learn C++ iteration or C++ loop through array in all these loops one by one. The easiest method is to use a loop with a counter variable that accesses each element one at a time. free xpo bol https://axiomwm.com

Nettet13. apr. 2024 · The remainder operator (also commonly called the modulo operator or modulus operator) is an operator that returns the remainder after doing an integer division. For example, 7 / 4 = 1 remainder 3. Therefore, 7 % 4 = 3. As another example, 25 / 7 = 3 remainder 4, thus 25 % 7 = 4. The remainder operator only works with integer operands.

Nettet14. apr. 2024 · int arr [] = {1, 2, 3}; int* p = & arr [0]; // p points to the first element of arr cout << *( p + 2); // outputs 3 In this example, we use pointer arithmetic to access the third element of the array arr. We start by assigning p to point to the first element of arr. We then add 2 to p, which advances the pointer by two integer-sized units.
