Parameters. You are filling the array with values more than 0 and less than 100. The solution would be to either move the definition of largest above main, or better, forward declare the function: Also, the sizeof(array) will not give you the number of elements in largest because that information is lost upon function call. Logical values and text representations of numbers that you type directly into the list of arguments are counted. You could move that expression up in the function call to compute and pass the length parameter: This may also be a typo, but you probably meant to store and print the maximum value: Put a declaration of largest() before main() to resolve the implicit declaration warning: The error error: expected expression before ']' token is caused by: To print the largest value, you need to store the result of largest() or use it as an argument to printf(): as arrays decays to pointers when passed as arguments. Note that this is OK because the condition in the for loop is i < n, which means that i can be at most 10, which is what you want. However, the compiler knows its size is 5 as we are initializing it with 5 elements. The max element is 6 2. Syntax: T max() const; Parameter: This function doesn't accept any parameter. max_element is the function you need. You use largest() in main() before you define it. printArray(arr, 5); // Pass array directly to function printArray. It returns an iterator to the max element in given range. Find max in Array Function C++ An array is a group of related data pieces kept in close proximity to one another in memory. They are also commonly known as " tailor-made functions " which are built only to satisfy the condition in which the user is facing issues meanwhile reducing the complexity of the whole program.
