Print 1 to 100 numbers in cpp

Print 1 to 100 numbers in cpp  is very simple and easy program to implement.

In this tutorial we are going to learn program which is Print alphabets 1 to 100.

Topic you need to know for this program is :

looping in c – for loop , while , do while loop

basic input output

logic to print 1 to 100 numbers in cpp

Using for loop we initialize start value to start = 1 and as we want number till end we write a condition start <= 100 so that loop will iterate 100 times and at each iteration we increment by 1 i.e. start ++. And in block of loop we print value of start so that we get numbers 1, 2 … 100

Algorithm  to print 1 to 100 numbers in cpp

1. Start
2. Initialize variable i=1
3. Write for loop with condition i <= 100
4. If condition true then print value of i
5. If condition get false skip loop
6. End

As above we seen how to print 1 to 100 numbers and it’s algorithm so let’s move to program to implement this.

Program to print 1 to 100 numbers in cpp

Output :-

Explanation :-

1. First line we include the preprocessor directives in our program

3. Declare variable

i => to hold numbers from 1 to 100

4. Next write for loop

for (i = 1 ; i <= 100 ; i ++)

At first iteration

i is initialized to 1 so that i= 1 , next condition is checked i <= 100 i.e. 1 <= 100. The condition become true and for block get executed

cout<<” “<<i; => 1 get printed

After block execution i is incremented by 1

At second iteration

i = 2 , next condition is checked 2 <= 100 which becomes true and loop block get executed.

cout<<” “<<i; => 2 get printed

After block execution i is incremented by 1

5. This will continue till value of i = 101.

While i = 101 condition 101 <= 100 which becomes false and execution come out of the loop.

6.Finally we the numbers from 1 to 100 printed on screen.
