WebIn C++, you can iterate through arrays by using loops in the statements. 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. WebThe function moves in a linear way, starting from the first element going towards the last one. For each element of the list value of 'pred' is checked. The search goes on until a mismatch for the ?pred? value is encountered. Data races. Either all the objects in the specified range or some of them are accessed by the function. Exceptions
