How many times will the following loop runfor(c = 1; c < 20; c=c+5) {document.write("C : " + c );document.write("<br />");
Question
How many times will the following loop run?
for(c = 1; c < 20; c = c + 5) {
document.write("C : " + c );
document.write("<br />");
}
Solution
To determine how many times the loop will run, we need to analyze the loop condition and the increment step.
The loop condition is c < 20, which means the loop will continue as long as the value of c is less than 20.
The increment step is c = c + 5, which means the value of c will increase by 5 in each iteration of the loop.
Starting with c = 1, the loop will run as follows:
-
Iteration 1:
c = 1,c < 20is true, so the loop runs. The output will be "C : 1". -
Iteration 2:
c = 6,c < 20is true, so the loop runs. The output will be "C : 6". -
Iteration 3:
c = 11,c < 20is true, so the loop runs. The output will be "C : 11". -
Iteration 4:
c = 16,c < 20is true, so the loop runs. The output will be "C : 16". -
Iteration 5:
c = 21,c < 20is false, so the loop terminates.
Therefore, the loop will run 4 times.
