IF Statement: Checks the value of data is less than or greater than. (in ranges).
example: can tell wether an input age is more than 18 and less than 60.

Switch Case: Checks the value of data that is prespecified. only equal to.

example: Can only generate output if the value matches. When the age is 18 or when the age is 60 . No comarison of data based on greater than or smaller than. Compares data based on equality.

The if statement can be used to test conditions so that we can alter the flow of a program. In other words: if a specific statement is true, execute this instruction. If not true, execute this instruction.

The switch statement is almost the same as an if statement. The switch statement can have many conditions. You start the switch statement with a condition. If one of the variable equals the condition, the instructions are executed. It is also possible to add a default. If none of the variable equals the condition the default will be executed

IF always working when it is with else part...
if(n1>n2) {
Printf("TRUE! n1 Is Greater");
} else {
Printf("False! n2 Is Greater");

Switch statement:
It is the MultiConditional control statement where it checks the value of switch choice if it is matched then that case will be Executed directly.
Otherwise it goes to default condition case.

switch(grade) {
case 1:
case 2:
printf("First Class");
case 3:
printf("Second Class");
case 4:printf("Fail");
printf("Result Declared");
