Max Value-Unit test

Design ideas

When debugging, as much as possible to take into account all possible situations, enter these conditions, to see the results of the program running

Source

#include <iostream>

using namespace Std;

int largest (int list[], int length);

int main ()

{

int list[100];

int lenght;

int i;

cout << "Please enter the length of the one-dimensional array:";

Cin >> Lenght;

if (lenght = = 0)

{

Cerr << "Array length cannot be zero!! "<< Endl;

return 0;

}

cout << "Please enter" << lenght << "integer:";

for (i = 0; i < lenght; i++)

{

CIN >> List[i];

}

cout << "The maximum value of this array is:" << largest (list, lenght) << Endl;

return 0;

}

int largest (int list[], int length)

{

int i, max=list[0];

for (i = 1; i < length; i++)

{

if (List[i] > Max)

{

max = List[i];

}

}

return Max;

}

Test

Issues found

Array length input is the character is the program error, also cannot be a floating-point number, negative, such as non-0 natural numbers;

The numbers in the array are calculated by the integer portion of the input floating-point number when the float is entered;

When Max's initial value is set to List "0", the value of I can start at 1;

Summarize

To treat each procedure with a special and rigorous attitude;

Should keep in mind that the computer is dead, and people are alive, the program is possible, can not let go of any detail!
