# Find Maximum and Minimum and Summation value from array

Did this problem from subeen vai’s book.

For maximum value:

```#include<stdio.h>
int find_max(int ara[],int n);
int main()
{

int ara[]={-100,0,53,22,83,23,89,-132,201,3,85};
int n=11;
int max=find_max(ara,n);
printf("%d\n",max);
return 0;
}

int find_max(int ara[],int n)
{
int max=ara[0]; //assume that first value of array according to index is maximum we will compare later with this
int i;
for(i=1;i<n;i++)
{
if(ara[i]>max) //here it is iterating the whole array
{
max=ara[i];
}
}

return max;
}```

For minimum value:

```#include<stdio.h>
int find_min(int array[],int n);

int main()
{
int array[]= {20,10,-123,980,60,50,70};
int n=7;
int min;
min=find_min(array,n);
printf("%d\n",min);
return 0;
}

int find_min(int array[],int n)
{
int min=array[0];
int i;
for(i=0; i<n; i++)
{
if(array[i]<min)
{
min=array[i];
}
}
return min;
}```

Summation:

```#include<stdio.h>
int find_sum(int ary[],int valu);
int main()
{
int ary[]={10,20,30};
int n=3;
int sum;
sum=find_sum(ary,n);
printf("%d\n",sum);
return 0;
}

int find_sum(int ary[],int n)
{
int i;
int sum=0;
for(i=0;i<n;i++)
{
sum=sum+ary[i];
}
return sum;
}```

Average:

Will give here

It would be a great help, if you support by sharing :)
