Write a c function for minimum and maximum value from the given input?

Answer 1

Assume that all your data were saved in array of type double and size 100:

int arrSize = 100;
double arr[arrSize] = {0.0};
...
for(int i = 0;...)
{
...
cin >> arr[i];//here you enter all elements using loop for

}
...

Out side of the function main you can define two functions max and min which take the array arr as argument

double min(const arr[], int arrSize)
{
double minimum = arr[0];
for (int j = 0; j < arrSize; j++)
{
if (minimum > arr[j])
{
minimum = arr[j];

}

}

return minimum;

}

double max(const arr[], int arrSize)
{
double maximum = arr[0];
for (int j = 0; j < arrSize; j++)
{
if (maximum < arr[j])
{
maximum = arr[j];

}

}

return maximum;

}
