Draw a flow chart and write down C program to take an array of 10 elements and print all
combinations of two elements whose sum is equal to 50.

Answer:
what is the correct answer
#include <stdio.h>
int main()
{
int arr[] = {1, 2, 3, 4, 5,6,7,8,9,10};
int length = sizeof(arr)/sizeof(arr[0]);
printf("Elements of given array: \n");
for (int i = 0; i < length; i++) {
printf("%d ", arr[i]);
}
return 0;
}
Explanation:
public class abc
{
static void findThePairs(int inputArray[], int inputNumber)
{
System.out.println("Pairs of elements whose sum is "+inputNumber+" are : ");
for (int i = 0; i < inputArray.length; i++)
{
for (int j = i+1; j < inputArray.length; j++)
{
if(inputArray[i]+inputArray[j] == inputNumber)
{
System.out.println(inputArray[i]+" + "+inputArray[j]+" = "+inputNumber);
}
}
}
}
public static void main(String[] args)
{
findThePairs(new int[] {4, 6, 5, -10, 8, 5, 20}, 10);
findThePairs(new int[] {4, -5, 9, 11, 25, 13, 12, 8}, 20);
findThePairs(new int[] {12, 13, 40, 15, 8, 10, -15}, 25);
findThePairs(new int[] {12, 23, 125, 41, -75, 38, 27, 11}, 50);
}
}
