Question

How for loop works?

Answer 1

Let's say you set up an array like:

fruits = ['banana', orange', 'grapefruit']

Then, let's suppose that you wanted to print out everything in that array in a nice formatted sentence. You could set up a for loop as follows:

for nameOfFruit in fruits:
print("I love", nameOfFruit)

Answer 2

For(initialization ;conditions ;increment /decrement)

In initialization you initialise a variable to specific value

In condition you specify a condition on which loop stops

Increment / detriment is used to increment value of the variable​

Eg
For(i=0;i<5;i++)
cout<<i;

Here the I is initialized to 0 and is printed and increments iteration by iteration the output would be
1234

Answer 3

Loop is a sequence of instructions that is repeated until a certain condition is reached. A for loop has two sections: a header specifying the iterating conditions, and a body which is executed once per iteration . The header often declares an explicit loop counter or loop variable, which allows the body to know which iteration is being executed. More on...
