Question

daily21. Computing 1. C programming

Please provide comments and write pre-condition and post-condition for the function.

Description Create a project called Daily21. Add a source file called daily21.c into the project. In this exercise, you will practice working with an array of integers. In the main function, you first need to create an integer array with 10 elements in t. Use a loop to read 10 integers from the user and store the values to the array (in the order of input). For example (in the screenshot below) the first element in the array stores 23, the next element stores value of 55, then the element stores the value of 87 and so on. You may assume that the user will only enter integers, but not characters, etc. Once the array is initialized, call a function to get the index number of the largest value in the array. For example, the largest element in the array is 98 (as shown below), so the return value of the function should be 5. This function should take the array you created in the main function as a parameter, the number of valid elements in the array, and return the index of the maximum value in the array. The array should not be changed after the function is called. Write the pre-condition and post-condition for the function (2 points, 1 point each). Print the result in the main program after calling the function as below CWindowslsystem321cmd.exe nter 10 integer values... Value 1: 23 Value 2: 55 Value 3: 87 alue 4: -12 Jalue 5: alue 6: 98 Value 7: 34 Value 8: 28 alue 9:-39 alue 10: 20 The index for the maxinun is 5 Press any key to continue .

Answer 1

#include <stdio.h>

//Function declaration
int getMaxValIndex(int arr[]);
int main( )
{

//declaring and initializing an array  
int arr[10];

//Declaring variable
int i;

printf("Enter 10 Integer values...\n");

//Displaying the array
for(i=0;i<10;i++)
{
printf("Value %d :",i+1);
scanf("%d",&arr[i]);
}

//Calling the function which returns the max element index value of an array
int maxValIndex=getMaxValIndex(arr);
printf("The index for the maximum is %d",maxValIndex);

return 0;
}

/* Function implementation which finds the maximum
* element index value of an array
*/
int getMaxValIndex(int arr[])
{
   //Declaring variable max and initialized with array first element
   int max=arr[0];
   int i,index=0;
  
   //This loop will finds the maximum elements index value.
   for(i=0;i<10;i++)
   {
       //Checking whether the array element is greater tham max value
       if(arr[i]>max)
       {
           max=arr[i];
           index=i;
       }

   }
return index;  
}
