Question

How many times will the body of the loop be executed?
var Total = 1;
for (intIndex = 1; intIndex < 7 ; intIndex += 2)
{
Total += intIndex;
}

Answer 1

Answer of this question given below:-

var Total = 1;
for (intIndex = 1; intIndex < 7 ; intIndex += 2)
{
Total += intIndex;
}

For this code, The body of the loop be executed 3 times.

1^st time :- intIndex =1

so, Total =Total + intIndex = 1+1 =2

2^nd time :- intIndex =3       (intTndex=intIndex +2=1+2=3   and 3<7)

so, Total =Total + intIndex = 2+3 =5

3^rd time :- intIndex =5    (intTndex=intIndex +2=3+2=5 and 5<7)

so, Total =Total + intIndex = 5+5 =10

Now,intIndex = intIndex+2=5+2 =7 then intIndex<7 condition not satisfy.

so,loop will be terminated.

Thus,The body of the loop be executed 3 times.
