WebThere are mainly 3 following ways to pass an array to a function in C/C++ 1. Formal parameter as pointers: In this approach, the function call accepts an address of an array and accesses it using pointer as an argument to the function call. The below snippet shows such a function. return_type functionName(type* array_name) { } WebSecond arguments is iterator pointing to the end of array arr. The third argument is the string value ‘strvalue’. It returns an iterator pointing to the first occurrence of the string strvalue in the array arr. Whereas, if the string value does not exist in the array then it will return an iterator pointing to the end of the array arr.

WebTo check if all the elements of an array are less than a given number, we need to iterate over all the elements of array and check each element one by one. For that we can use a STL Algorithm std::all_of (), which accepts the start & end iterators of an array as first two arguments. As this 3rd argument it will accept a Lambda function. WebYou can also use pointers to access arrays. Consider the following array of integers: Example int myNumbers [4] = {25, 50, 75, 100}; You learned from the arrays chapter that you can loop through the array elements with a for loop: Example int myNumbers [4] = {25, 50, 75, 100}; int i; for (i = 0; i < 4; i++) { printf ("%d\n", myNumbers [i]); }

WebFor this we will first set the pointer variable ptr to point at the starting memory location of std variable. For this we write ptr = std; .
