Write repeat-until equivalent using while loop.

Question

repeat-until execute the statements inside the loop till the condition is false.

whereas while loop executes the statements inside loop till the condition is true.

I need repeat-until equivalent of while loop with appropriate example.

Answer 1

pass the condition with a negation

while ( !(condition))

this will execute the block until the condition is false.

example:

i= 0
while( !(i==5)) // run until i isn't equal to 5
{ cout<<i;
i++;
}

output: 01234

Answer 2

In python

myVar = 0
while True :
myVar += 1
if myVar == 5 :
print 'myVar is '+str(myVar)
break
else:
print 'printing "else" block'

in c++

#include <iostream>

using namespace std;

int main()
{
int myVar = 0;
while(true)
{
if(myVar ==5){
cout<<myVar;
break;
}
else{
cout<<"printing else block \n";
}

myVar++;
}
}
