Answer:
#include <iostream>
#include <vector>
using namespace std;
/* Define your function here */
vector<int> GetUserValues(vector<int>& userValues, int numValues) {
int tmp = 0;
vector<int> newVec;
for(int i = 0; i < numValues; i++) {
cin >> tmp;
newVec.push_back(tmp);
}
return newVec;
}
void OutputIntsLessThanOrEqualToThreshold(vector<int> userValues, int upperThreshold) {
for (int i = 0; i < userValues.size(); ++i) {
if(userValues.at(i) < upperThreshold) {
cout << userValues.at(i) << " ";
}
}
cout << endl;
}
int main() {
vector<int> userValues;
int upperThreshold;
int numValues;
cin >> numValues;
userValues = GetUserValues(userValues, numValues);
cin >> upperThreshold;
OutputIntsLessThanOrEqualToThreshold(userValues, upperThreshold);
return 0;
}
Explanation:
Perhaps their is a better way to code this, but I couldn't figure out what to do with the pointer in the first function.
Because t=1/f. So. Do you know ? B
Your computer will absolutely benefit. Disk Cleanup is a Windows tool that lets you clean junk files and temporary files that are no longer needed, thus increasing space and performance.
Answer:
#include<iostream>
#include <vector>
#include <list>
using namespace std;
int main(){
int a[10]={0,1,2,3, 4, 5, 6, 7, 8, 9 };
std::vector<int> v (&a[0],&a[0]+10);
std::list<int> l (&a[0],&a[0]+10);
int b[10];
for(int i=0;i<10;i++){
b[i]=a[i];
}
std::vector<int> v2(v);
std::list<int> l2(l);
for(int i=0;i<10;i++){
b[i]+=2;
}
for(int i=0;i<10;i++){
v2[i]+=3;
}
for (std::list<int>::iterator it = l2.begin(); it != l2.end(); it++)
*it=*it+5;
cout<<"Each containers value are: "<<endl;
cout<<"1st array: "<<endl;
for(int i=0;i<10;i++){
cout<<a[i]<<" ";
}
cout<<"\n 1st vector: \n";
for(int i=0;i<10;i++){
cout<<v[i]<<" ";
}
cout<<"\n 1st List is:\n";
for (std::list<int>::iterator it = l.begin(); it != l.end(); it++)
cout << *it << ' ';
cout<<"\n 2nd array: "<<endl;
for(int i=0;i<10;i++){
cout<<b[i]<<" ";
}
cout<<"\n 2nd vector:\n";
for(int i=0;i<10;i++){
cout<<v2[i]<<" ";
}
cout<<"\n 2nd list:\n";
for (std::list<int>::iterator it = l2.begin(); it != l2.end(); it++)
cout << *it << ' ';
return 0;
}
Explanation:
- Initialize an array, a vector and a list of type integer
.
- Create a 2nd array, vector, and list as a copy of the first array, vector, and list.
- Increase the value of each element in the array by 2
, vector by 3 and list by 5.
- Finally display the relevant results.
