6.11.5: Functions with vector parameters. CODE++ ONLY
Define a function isSumEqual() that takes one integer vectorparameter and one integer parameter. The function computes the sumof the vector's elements. Then, the function returns true if thesum is equal to the integer parameter, and returns falseotherwise.
Ex: If the input is 4 6 -3 10 -4 10, the vector has 4 elements{6, -3, 10, -4}, and the integer parameter is 10. Then, the outputis:
False, the sum of all the elements is not equal to 10.
CODE:
#include <iostream>#include <vector>using namespace std;
bool isSumEqual(vector<int> inVector, int x){ int sum=0; for(auto & i : inVector) { if(i>x){ sum+=i; } }
if(sum%2!=0){ return true; }
else{ return false; }}
int main() { vector<int> inVector; int size; int input; int i; int x; bool result;
// Read the vector's size, and then the vector'selements cin >> size; for (i = 0; i < size; ++i) { cin >> input; inVector.push_back(input); }
cin >> x;
result = isSumEqual(inVector, x);
if (result) { cout << "True, the sumof all the elements is equal to " << x << "." <<endl; } else { cout << "False, the sumof all the elements is not equal to " << x << "."<< endl; }
return 0;}

For input 4 6-3 10-410, the first integer, 4, is the length of the vector. The next four values are the vector's elements, (6,-3, 10,-4}. The last input value, 10, is the integer parameter. The function finds that the sum of all the vector's elements is 9. 9 is not equal to 10, so the function returns false. Thus, the program outputs: False, the sum of all the elements is not equal to 10. Not all tests passed. ✓ 1: Compare output Input Your output X 2: Compare output Input Output differs.
