C++ Tutorial/Operators statements/continue
break and continue statements
#include <iostream>
using namespace std;
int main()
{
int count = 0;
while (true)
{
count += 1;
//end loop if count is greater than 10
if (count > 10)
break;
//skip the number 5
if (count == 5)
continue;
cout << count << endl;
}
return 0;
}Set up 3 stop conditions for the loop: break and continue
#include <iostream>
using namespace std;// this file uses std::cout,
// std::cin, std::endl, etc.
int main()
{
unsigned short small = 1;
unsigned long large = 10;
unsigned long skip = 2;
unsigned long target = 8;
const unsigned short MAXSMALL=65535;
while (small < large && large > 0 && small < 65535)
{
small++;
if (small skip == 0)// skip the decrement?
{
cout << "skipping on " << small << endl;
continue;
}
if (large == target) // exact match for the target?
{
cout << "Target reached!";
break;
}
large-=2;
}
cout << "\nSmall: " << small << " Large: " << large << endl;
return 0;
}skipping on 2 skipping on 4 Target reached! Small: 5 Large: 8
Using the continue statement with do while loop
#include <iostream>
#include <iomanip>
#include <cctype>
#include <limits>
using std::cout;
using std::endl;
using std::setw;
int main() {
cout << endl
<< setw(13) << "Character "
<< setw(13) << "Hexadecimal "
<< setw(13) << "Decimal "
<< endl;
cout << std::uppercase;
unsigned char ch = 0;
do {
if(!std::isprint(ch))
continue;
cout << setw(7) << ch
<< std::hex
<< setw(13) << static_cast<int>(ch)
<< std::dec
<< setw(13) << static_cast<int>(ch)
<< endl;
} while(ch++ < std::numeric_limits<unsigned char>::max());
return 0;
}Character Hexadecimal Decimal
