Question

I am writing a program that reads ten integers from standard input, and determines if they are going up or down or neither. Can I get some help? I have supplied what I have already.

#include <stdio.h>

#include <string.h>

#include <stdlib.h>

int isGoingUp(int [a]);

int isGoingDown(int [b]);

int main(void) {

int array[10];

printf("Enter ten integers : ");

for (int a = 0; a < 10; a++) scanf("%d", &array[a]);

if (isGoingUp(array) == 1)

printf("The values are going up\n");

else if (isGoingDown(array) == 1)

printf("The values are going down\n");

else

printf("The values are neither going up or going down\n");

return 0;

}

Program:-

#include <stdio.h>

#include <string.h>

#include <stdlib.h>

//implemented the isGoingUp() function to check array is in ascending order
int isGoingUp(int a[])
{
    int i;
    for(i = 1; i< 9 ; i++){
      
        if(a[i] < a[i-1])
        return 0;
    }
    return 1;
}

//implemented the isGoingDown() function to check array is in descending order
int isGoingDown(int b[])
{
    int i;
    for(i = 1; i< 9 ; i++){
      
        if(b[i] > b[i-1])
        return 0;
    }
    return 1;
}

//drive function it will scan's 10 integers from the input and check whether the array is going up or down or neither of them
int main(void) {

int array[10];

printf("Enter ten integers : ");

for (int i = 0; i < 10; i++)
     scanf("%d", &array[i]);

if (isGoingUp(array) == 1)

printf("The values are going up\n");

else if (isGoingDown(array) == 1)

printf("The values are going down\n");

else

printf("The values are neither going up or going down\n");

return 0;

}

Output:-

Enter ten integers : 9 88 7 6 78 4 3 2 8

The values are neither going up or going down

Enter ten integers : 1 2 3 4 5 6 7 8 9 10

The values are going up

Enter ten integers : 10 9 8 7 6 5 4 3 2 1

The values are going down
