I have included both Funtion to find maximum integer and Function to find minimum integer seperately.

I have included the explanation in comments.

Here is the code to find the minimum integer with function.

#include <iostream>
using namespace std;

int MinToFind(int a[],int n) //function to find smallest integer
{
        int i, min;
        min = a[0];// thinking that first number is minimum
        for(i=1;i<n;i++)
        {
                if(a[i]<min)// //if present number is smaller than minimum number
                        min =a[i];//smallest is assigned to number
        }
        return min; //returns to function
}
int main()
{
        int i, array[4], size=4, min;  // initializing int, array size and min

        cout<<"Enter four integers\n";
        for(i=0;i<size;i++)
        cin>>array[i];

        min = MinToFind(array,size); //min function is being called where we declared it

        // max element is printed
        cout<<"Smallest integer is " << min << "\n";

return 0;
}

Screenshot to the output:

main.cpp 1 #include <iostream> 2 using namespace std; 3 4. int MinToFind(int a[], int n) //function to find smallest integer { 7 int i, min; min a[@];// thinking that first number is minimum for(i=1;i<n;i++) { } 10 if(a[i] <min)// //if present number is smaller than minimum number 11 min =a[i];//smallest is assigned to number 12 } 13 return min; //returns to function 14 15 int main() 16 { 17 int i, array[4], size=4, min; // initializing int, array size and min 18 19 cout<<"Enter four integers\n"; 20 for(i=0;i<size;i++) 21 cin>>array[i]; 22 23 min MinToFind(array,size); //min function is being called where we declared it 24 25 // max element is printed 26 cout<<"Smallest integer is << min << "\n"; 27 28 return 0; 20 ? input 1 2 3 4 Smallest integer is 1 .Program finished with exit code 0 Press ENTER to exit console./

Here is the code to find the maximum integer with function.

#include <iostream>
using namespace std;
int MaxToFind(int a[],int n) //function to find largest integer
{
        int i, max;
        max = a[0];// thinking that first number is maximum
        for(i=1;i<n;i++)
        {
                if(a[i]>max) //if present number is greater than maximum number
                        max =a[i]; //max is assigned to number
        }
        return max; //returns to function
}

int main()
{
        int i, array[4], size=4, min; // initializing int, array size and max

        cout<<"Enter four integers\n";
        for(i=0;i<size;i++)
        cin>>array[i];

        max = MaxToFind(array,size); //max function is being called where we declared it

        // max element is printed
        cout<<"Largest integer is " << max << "\n";


return 0;
}

Screenshot to the output:

main.cpp 1 #include <iostream> 3 int MaxTofind(int ai], int n) //functiðh to find largest integer 5 6 int i, max; max = a[@];// thinking that first number is maximum for(i=1;i<n;i++) a 7 { } } g if(a[i]>max) //ik present number is greater than maximum number 10 max =a[i]; //max is assigned to number 11 12 return max; //returns to function 13 14 15 int main() 16 { 17 int i, array[4], size=4, min; // initializing int, array size and max 18 19 cout<<"Enter four integers\n"; 20 for(i=0;i<size;i++) 21 cin>>array[i]; 22 23 max = MaxtoFind(array,size); //max function is being called where we declared it 24 25 // max element is printed 26 cout<<"Largest integer is << max << "\n"; 27 28 29 return @; 30 } input Enter four integers 3 9 8 5 Largest integer is 9 Program finished with exit code 0 Press ENTER to exit console./
