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.

My question is how I write the code to find the max value of the array elements without comparing the last element to something outside the memory block? even if that's IFR in the categorical outlooks? C program to find the largest number in an array using a function and without it. Ltd. All rights reserved. the %d format specification implies you want to In the following example, we will find the maximum value of an array (arr). Say max () function is used to find maximum between two numbers. By using our site, you ? Connect and share knowledge within a single location that is structured and easy to search. Then, this program displays the largest element of that array using loops. int find_maximum(int a[], int n) { int c, index = 0; for (c = 1; c < n; c++) if (a[c] > a[index]) index = c; int main(){ long array[100], *maximum, size, c, location = 1; printf("Enter the number of elements in array\n"); scanf("%ld", &size); for (c = 0; c < size; c++) scanf("%ld", &array[c]); for (c = 1; c < size; c++) { if (*(array+c) > *maximum) { *maximum = *(array+c); location = c+1; } }, printf("Maximum element found at location %ld and its value is %ld.\n", location, *maximum); return 0;}. Is there a reason beyond protection from potential corruption to restrict a minister's ability to personally relieve and appoint civil servants? { The complexity of above code is O(n) as the time used depends on the size of input array or in other words time to find maximum increases linearly as array size grows. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Manage Settings You can easily modify the program to print the largest index at which it's present. you do not assign a value to i. Parewa Labs Pvt. In this case, a declaration of array as variable length array after the scanf() call would be more appropriate: Since there will never be more than 10 players: "There are never more than 10 players in the game" - You could also leave array of fixed size with 10 elements and analyze the input of N in a loop and ask the user to reinput a valid number between 0 and 10 if N isn't in this range. You have an error and warnings .. the error is clearly more important. Algorithm to get max value: we assume that it's present at the beginning of the array. and Get Certified. Is there a legal reason that organizations often refuse to comment on an issue citing "ongoing litigation"? Note that the current maximum value is initialized with the value of the first element in the array and modified when the if condition evaluates true. Happy to help :) Also, remember to upvote the answers that helped you and.
