Explain the working of ‘ if’ statement and ‘if-else’ statement

1.	Explain the working of ‘ if’ statement and ‘if-else’ statement with examples.
Answer» Example for ‘if’ statement: # include <iostream.h> void main () { int a = 100; int b = 200; if (b > a) { cout <<"B is greater than A"; } } Result: B is greater than A In the above example the condition in the if statement returns a true value and so the text “B is greater than A” is displayed. Example for ‘if else’ statement: #include <iostream.h> void main () { int a = 10; int b = 20; if(a>b) { cout <<"A is greater than B"; } else { cout <<"B is greater than A"; } Result: B is greater than A. In the above example, the “if’ condition is false so the code in the “else” part is executed.

Answer»

Example for ‘if’ statement:

# include <iostream.h>

void main ()

{

int a = 100;

int b = 200;

if (b > a)

{

cout <<"B is greater than A";

}

Result:

B is greater than A In the above example the condition in the if statement returns a true value and so the text “B is greater than A” is displayed.

Example for ‘if else’ statement:

#include <iostream.h>

void main ()

{

int a = 10;

int b = 20;

if(a>b)

{

cout <<"A is greater than B";

}

else

{

cout <<"B is greater than A";

}

Result: B is greater than A. In the above example, the “if’ condition is false so the code in the “else” part is executed.
