Write the definition of a function named issorted that receives three arguments: an array of int , an int that indicates the number of elements of interest in the array , and a bool. if the bool argument is true then the function returns true if and only if the array is sorted in ascending order. if the bool argument is false then the function returns true if and only if the array is sorted in descending order. in all other cases the function returns false. you may assume that the array has at least two elements.

The method definition to this question can be given as:

Method Definition:

bool isSorted(int a[], int n, bool status)  //function definition

{

//function body

bool flag = true;          //define Bool(Boolean) variable.

if(status == true)  //check condition.

{

for (int i=0; i<n-1; i++)         //loop for search

{

if (a[i] > a[i+1])         //check array elements

{

flag = false;         //change bool variable value.

}

}

}

else       //else block

{

for (int i=n-1; i > 0; i--)  //loop

{

if (a[i] > a[i-1])   //if block

{

flag = false;     //change bool variable value.

}

}

}

return flag;      //return value.

}  

Explanation:

In the above method definition firstly we define the method that is isSorted(). This method returns true or false value because its return type is bool. In the method, we define the bool variable that is flag. Then we use the condition by using conditional statements. in the if block we check that if status equal to true then we use the for loop in the for loop we define variable i that is used for search array elements it will go to n-1 that is the total number of an array is decrement by 1. In this loop, we use the if condition that is if elements of a[i] is greater then a[i+1] flag will return false. In the else block we use the for loop for search array elements in this loop we use the if block that checks that elements of a[i] is greater then a[i-1]. if it is true it returns false. end of loop end of else block the function will return value.
