Problem(s) with an array!!
Hi everyone,
Before you read my code, i want to mention that the main function was giving to me, that means that i should create all the functions presented in main.that is what the exercise requires.
No one of the option within the choice_operation function is done correctly, I mean, it list huge numbers like 418033 or something.
Code:
#include <stdio.h>
#include <stdlib.h>
#define SIZE 3
void read_array(int []);
void sort_array(int []);
int search(int, int[]);
void choice_operation(int []);
int main(){
int ar[SIZE]; //array declaration (SIZE is constant)
read_array(ar); //read array elements
sort_array(ar); //sort the array
choice_operation(ar); //display a list of operations
system("PAUSE");
return 0;
}
void read_array(int x[]){
for (int i = 0 ; i < SIZE ; i++)
scanf("%d",&x[i]);
}
void sort_array(int x[]){
int index,i,j;
for (i = 1 ; i < SIZE ; i++){
x[i] = index;
for(j = i - 1 ; j < 0 ; j--){
if (x[j] > x[i])
x[j+1] = x[j];
}
x[j] = index;
}
}
int search (int v,int x[]){
for (int i = 0 ; i < SIZE ; i++){
if (x[i] == v)
return(i);
}
return(-1);
}
void choice_operation(int x[]){
int y,sum = 0,a = 0,v;
printf("To display the max and the min of the array, enter 1\n");
printf("To know a position of a value, Enter 2\n");
printf("To find the average, Enter 3\n");
printf("To list the elements of the array, Enter 4\n");
printf("To exit, Enter any other character.\n");
scanf("%d",&y);
switch(y){
case 1:
printf("the max is %d, and the min is %d\n",x[0],x[SIZE-1]);
break;
case 2:
printf("Enter a value to know its position within the array:\n");
scanf("%d",&v);
a = search(v,x);
if(a != -1)
printf("the positions of %d is %d\n",v,a);
else
printf("this element does not belong to the array\n");
break;
case 3:
for (int i = 0 ; i < SIZE ; i++)
sum += x[i];
printf("The average is %d\n",(sum / SIZE));
break;
case 4:
for(int i = 0 ; i < SIZE ; i++)
printf("%d\n",x[i]);
break;
default:
printf("The program ends.\n");
}
}
