Question

3. A tor loop is useful when you know in advance the number of iterations to be executed. The tor loop consists of three parts each of which is separated by a semicolon (:). The first part is initialization of the variable for iteration, the second part is a test of the iteration variable and if this test fails, the loop is finished. The third part is a counter for the iteration variable. A block can be followed after the for statement (no semicolon multiple statemernts for each iteration for initial value; condition counter to execute nti statemznt: The following program prints an integer value from 15 to 20. inciude <8tdio.h nt nain ( int i 1: for [i-5 ; i<11;i++) printf("dn", i+10): 0: Write a code to print odd integers starting from 1 to 21 Hint tor [1-0;1(-10;2++) print (2 tlmes 1 + 1)

Answer 1

/*

As for loop is already explained you. Please understand more from below example
int i;
for(i=0;i<=3;i++)

This loop will run 4 times and the value of i will change and it will be
0,1,2,3

You can generate odd number from any number x
like 2*x+1

Lets see some examples
2*1+1=3(odd)
2*2+1=5(odd)
2*3+1=7(odd)

so using value of i and formula 2*i+1 we can generate odd integers for all values of i

so in this program the values of i will be 0,1,2,3,4,5,6,7,8,9,10
And I wrote 2*i+1 in printf which will odd value for all i
Sample Output:
1
3
5
7
9
11
13
15
17
19
21

//C Program to print Odds Create a odd.c file and copy below code and execute

#include<stdio.h>
int main()
{
//Declaring a variable i
int i;
//A for loop which will run 11 times, block of loop will print odd integers between 1 and 21
for(i=0;i<=10;i++)
{
//Printing odd value
printf("%d\n",(2*i+1));
}

return 0;
