In this post, we will write a C program to find the minimum and maximum numbers in an array.

C Program to Find Minimum and Maximum Number in an Array

In this program, we will make a function return two values, the maximum and minimum values, and store them in another array. Thereafter, the array containing the maximum and minimum values will be returned from the function.

C functions cannot return more than one value. But what if you want a function to return more than one value? The solution is to store the values to be returned in an array and make the function return the array instead.

Let's create a file named findminmax.c and add the following source code to it:

# include <stdio.h> #define max 10 int *maxmin(int ar[], int v); void main() {	int arr[max];	int n,i, *p;	printf("How many values? ");	scanf("%d",&n);	printf("Enter %d values\n", n);	for(i=0;i<n;i++)	scanf("%d",&arr[i]);	p=maxmin(arr,n);	printf("Minimum value is %d\n",*p++);	printf("Maximum value is %d\n",*p); } int *maxmin(int ar[], int v) {	int i;	static int mm[2];	mm[0]=ar[0];	mm[1]=ar[0];	for (i=1;i<v;i++)	{	if(mm[0] > ar[i])	mm[0]=ar[i];	if(mm[1]< ar[i])	mm[1]= ar[i];	}	return mm; } 

To compile and run the above C program, you can use C Programs Compiler Online tool.

Output:

How many values? 5 Enter 5 values 10 20 30 40 50 Minimum value is 10 Maximum value is 50
