C goto statement

The goto statement is known as jump statement in C language. It is used to unconditionally jump to other label. It transfers control to other parts of the program
It is rarely used today because it makes program less readable and complex
Syntax:

goto label;
goto example
 Let's see a simple example to use goto statement in C language. 
#include <stdio.h>
void main() {  
int age;    
ineligible:  
printf("You are not eligible to job!\n");    
printf("Enter you age:\n");  
scanf("%d", &age);  
if(age<20)  
goto ineligible;  
else  
printf("You are eligible to job!\n");    
 }   
 Output:
You are not eligible to job!
Enter you age:
15
You are not eligible to job!
Enter you age:
35
You are eligible to job!

Type Casting in C

Type casting allows us to convert one data type into other. In C language, we use cast operator for type casting which is denoted by (type).
Syntax:

(type)value;
Without Type Casting: 
int f= 27/5;  
printf("f : %d\n", f ); 
Output: 5
With Type Casting: 
float f=(float) 27/5;  
printf("f : %f\n", f ); 
Output: 5.400000
Type Casting example:
Let's see a simple example to cast int value into float. 
#include <stdio.h>
void main(){      
float f= (float)27/5;  
printf("f : %f\n", f );         
}
Output:
f : 5.400000
