Write a program in C to print " Happy Birthday " 10 times ( Using while loop , do ... while loop , for loop or statements)

This can be done in 3 different ways.

1 - way

#include<stdio.h> main() { int i = 1; while (i < = 10) { printf("Happy Birthday \n"); i = i +1; } return(0); }

2 - way

#include<stdio.h> main() { int i = 1; do { printf("Happy Birthday \n"); i = i + 1; } while (i < = 10) return(0); }

3 - way

#include<stdio.h> main() { int i; for (i = 1; i < = 10; i = i+1) { printf("Happy Birthday \n"); } return(0); }

Output is same in all above 3 different loop.

Output :-
Happy Birthday
Happy Birthday
Happy Birthday
Happy Birthday
Happy Birthday
Happy Birthday
Happy Birthday
Happy Birthday
Happy Birthday
Happy Birthday

for loop or for statement

The syntax of this statement as follows :-

for(exp1; exp2; exp3)
{
statements;
}

Explaination :-
In the for statement, there are 3 expression,
exp1 is used to initialize or to start the index parameter.
exp2 represents a condition to be satisfy for the execution of the loop.
exp3 is used to change the value of index parameter.

do ........... while loop in C

The syntax of this statement as follows :-

do
{
statements:
}
while(expression);

Explaination :-
In do ....... while loop first the statement are executed and then the expression in the bracket tested. The execution stops if the expression becomes false.

while loop in C program

The syntax of this statement as follows :-

1)
while (expression)
{
statements;
}

Explaination :-
In while statement the bracket expression is a condition which is tested, if the condition is true the loop gets executed. The execution stops when the condition become false.

Repetitive statements in C

In some C program, we have to repeat certain step during program execution. This can be done with the help of the repetitive statements or loop statements. They are While, do ......... while, for.

The syntax of this statement as follows :-

1)
while (expression)
{
statements;
}

2)
do
{
statements:
}
while(expression);

3)
for(exp1; exp2; exp3)
{
statements;
}

pf = bp * 0.08;
break;

case 'w' :
hra = bp * 0.05;
pf = bp * 0.07;
break;

default :
hra = 0.0;
pf = 0.0;
}
ns = bp + hra - pf;
printf("Net salary = Rs. %f \n", ns);
}

switch ................. case :-

It is a generalization of the if ............... else statement. It is a compound statement which gives some alternative course of action. The keyword switch is followed by bracket showing a variable name and the keyword case is followed by an integer or a single character constant called as the case label.
The keyword break takes the control out of the switch structure.

For eg :-

Output :-
Enter any two numbers
20.5 32.3
The maximum number is 32.300000

if ........................ else statement

The syntax is

if (expression)
statement set 1;
else
statement set 2;

The bracket contains a condition, the condition is tested, if the condition is true then statement set 1 gets executed and statement set 2 ignored.
If the condition is false then statement set 2 gets executed and statement set 1 is ignored.

Note that :-
1) Statement set 1 is called as the "if block" and statement set 2 is called as "else block"
2) else should be written below if.
3) Both the statement sets 1 and 2 should be written little towards the right side. This is the formatting convention.
4) Both the statement set should be enclosed in a pair of braces { } but braces are not required in case of single statement.
5) Both the statement sets must end with semicolon ;

Control Statement in 'C'

A computer program in usually executed in the same order in which the statement appear in the program but in some programs it is necessary to conduct a logical test and then the order of execution should be decided. This is called as conditional execution and it is done with the helps of control statement.

We have the following control statement.
1) if...........................else,
2) switch.........................case,
3) while,
4) do...................while,
5) for,
