Find the oldest age in the family

Find the maximum age among N family members given as space-separated integers

Understand the Problem

Problem Statement

A family consists of N members. Their ages are passed as input separated by a space. Write a program to find the age of the oldest member in the family.

Constraints

All ages must be between 0 and 110 (inclusive)
Input consists of N space-separated integers
N can be any positive integer

Examples

Example 1

Input

10 78 56 87 32

Output

Explanation

Among the ages 10, 78, 56, 87, and 32, the oldest age is 87.

Example 2

Input

25 45 33 67 18

Output

Explanation

Among the ages 25, 45, 33, 67, and 18, the oldest age is 67.

Example 3

Input

100 95 88

Output

Explanation

Among the ages 100, 95, and 88, the oldest age is 100.

Solution

#include <stdio.h>
#include <limits.h>

int main() {
    int age;
    int max_age = INT_MIN;
    
    // Read ages until end of input
    while (scanf("%d", &age) == 1) {
        if (age > max_age) {
            max_age = age;
        }
    }
    
    printf("%d", max_age);
    return 0;
}

Time:O(n)

Space:O(1)

Approach:

The C solution reads integers from standard input using scanf() in a loop. It initializes max_age to the smallest possible integer value. For each age read, it compares with the current maximum and updates max_age if the new age is larger. Finally, it prints the maximum age found.
