How do we find the lowest?

Question

For example
int x[4] = { 3, 9, 7 , 10}
How do I find which is the smallest number?

This is regarding the ticket office question in c++ .

Answer 1

Kruti

Store first value in a variable and compare with next value. If next value is less than 1st value then that would be smallest number otherwise 1st value will be smallest number.

int x[4] = {3, 9, 7, 10};

int min = x[0];

for (int i = 0; i < 4; i++) {
if (x[i] < min)
min = x[i];
}

cout << min;

Answer 2

Kruti

Doesn't matter on order just try shared logic.

Answer 3

And what if the values are not in increasing order?
For example
int x[4] = { 12, 7, 20 , 1}

Like when four numbers are randomly selected by the user?

Answer 4

Kruti if values are not in sorting or then u can use any sorting techniques to sort the values u can easily find min max

or u can use STL library
std::min() , std::max()

Answer 5

#include <iostream>
using namespace std;

int main() {
int k[5] = {7, 2, 8, 1, 4};
int min = *k;
for (int i=0;i<5;i++) {
if (k[i] < min) min = k[i];
}
cout << min;
return 0;
}
