How check four number in c who is bigger?

Answer 1

In order to determine which of four number is bigger you need 16 if statements arranged in a nested if statement. That exceeds the complexity of just sorting it in an array. Here is a solution using a simple array sort.

int array[] = {7, 2, 27, 4};

int i, swap;

do {

swap = 0;

for (i = 0; i < 4; ++i) {

if (array[i]<array[i+1]) {

swap=array[i];

array[i]=array[i+1];

array[i+1]=swap;

swap=1;

}

}

} while (swap == 1);

printf ("%d\n", array[0]);
