Program Code - else..if statement

Program Code - else..if statement

The else..if statement is useful when you need to check multiple conditions within the program, nesting of if-else blocks can be avoided using else..if statement.

1. else and else..if are optional statements, a program having only "if" statement would run fine.
2. else and else..if cannot be used without the "if".
3. There can be any number of else..if statement in a if else..if block.
4. If none of the conditions are met then the statements in else block gets executed.
5. Just like relational operators, we can also use logical operators such as AND (&&), OR(||) and NOT(!).

#include <stdio.h>
int main()
{
   int j1, j2;
   printf("Input the value of j1:");
   scanf("%d", &j1);
   printf("Input the value of j2:");
   scanf("%d",&j2);
   if (j1 !=j2)
   {
	printf("j1 is not equal to j2\n");
   }
   else if (j1 > j2)
   {
	printf("j1 is greater than j2\n");
   }
   else if (j2 > j1)
   {
	printf("j2 is greater than j1\n");
   }
   else
   {
	printf("j1 is equal to j2\n");
   }
   return 0;
}
