Hi! :)
Not the best I've made, but you can make it better :D. The main idea is working, but my code, of course, has some deficiencies. You can complete if if you want ;).
#include <stdio.h>
#include <limits.h>
typedef struct
{
int a;
int b;
int indexA;
int indexB;
} ret;
ret SrcSum(int Arr[], int N, int x)
{
ret src;
src.a = src.b = INT_MIN;
printf("size: %d\n", N);
int i = 0, j = 0;
int index_a = -1, index_b = -1;
while( i < N )
{
j = 0;
while( Arr[i]+Arr[j] != x)
j++;
if(j<N)
{
src.a = Arr[i];
src.b = Arr[j];
src.indexA = i;
src.indexB = j;
break;
}
i++;
}
return src;
}
void main()
{
int size = 10;
int t[size];
int index;
for( index = 0; index < size; index++)
t[index] = index;
int sr;
printf("\nWhat num to search: "); scanf("%d",&sr);
ret nums = SrcSum(t, size, sr);
if( nums.b == INT_MIN )
printf("\nSorry, no matches found.\n\n");
else printf("\n%d + %d = %d, index: %d %d", nums.a, nums.b, sr, nums.indexA, nums.indexB );
}
I hope I could help you.
