printing the largest value in array - arrays

Question

I was having a trouble regarding to printing out the largest number in array in c language and i don't know how to do it while using loop. Please help me thanks
here is my code
#include <stdio.h>
void main() {
int Lnum, size;
printf("Enter the size: ");
scanf("%d", &size);
int nums[size];
for (int i = 0; i < size; i++) {
scanf("%d", &nums[i]);
}
printf("\nReversed = ");
for (int i = size - 1; i >= 0; i--) {
printf("%d ", nums[i]);
}
for (int a = 0; a < size; a++) {
for (int i = 0; i < size; i++) {
if (nums[a] > nums[i]) {
Lnum = nums[a];
}
}
}
printf("\nLargest element = %d", Lnum);
}

Answer 1

The algorithm for determining the largest element in an array goes as follows.
Use the value of the first array element as a start value for the biggest number.
Go over the rest of the array and check for each element if it is a bigger number.
When a bigger number is found use the bigger number for further comparisons.
#include<stdio.h>
void main(){
int Lnum, size;
printf("Enter the size: ");
scanf("%d", &size);
int nums[size];
for(int i=0; i<size; i++){
scanf("%d", &nums[i]);
}
printf("\nReversed = ");
for(int i=size-1; i>=0; i--){
printf("%d ", nums[i]);
}
Lnum = nums[0]; // Assume first element to be the largest element
for(int a=1; a<size; a++){ // start loop with second element
if(Lnum < nums[a]) { // check if current element is larger
Lnum = nums[a]; // found larger element, it is now the largest element of all inspected element
}
}
printf("\nLargest element = %d", Lnum);
}
Output:
Enter the size: 3
1 2 3
Reversed = 3 2 1
Largest element = 3
