Use assert inside a for loop to check an array
#include <iostream>
#include <algorithm>
#include <cassert>
using namespace std;
int main() {
int a[1000];
int i;
for (i = 0; i < 1000; ++i)
a[i] = 1000 - i - 1;
sort(&a[0], &a[1000]);
for (i = 0; i < 1000; ++i)
assert (a[i] == i);
return 0;
}Use assert to check
#include <iostream>
#include <cassert>
#include <deque>
#include <algorithm> // For find
using namespace std;
int main()
{
char x[5] = {"a", "r", "e", "q", "t"};
deque<char> deque1(&x[0], &x[5]);
// Search for the first occurrence of the letter e:
deque<char>::iterator where = find(deque1.begin(), deque1.end(), "e");
assert (*where == "e" );
cout << "Ok." << endl;
return 0;
}Ok.
Using the STL generic reverse algorithm with a string and assert the correctness
#include <iostream>
#include <string>
#include <cassert>
#include <algorithm> // For reverse algorithm
using namespace std;
int main()
{
string string1 = "abc";
reverse(string1.begin(), string1.end());
assert (string1 == "cba");
return 0;
}
