if...else if condition

The if-else-if Ladder. A common programming construct that is based upon nested ifs is the if-else-if ladder. It looks like this. The conditional expressions are evaluated from the top downward. As soon as a true condition is found,



syntax
if(condition1)
{
   statement
}
else if(condition2)
{
   statement
}
--------------------------
--------------------------
else
{
  default statement
}



Flow chart





Example for if...else if condition in[c-program]


#include< stdio.h > /* header file */
#include< conio.h > /* header file */

void main() /* main function start*/
{
  int mark;

  clrscr();

  printf("enter the mark \n ");
  scanf("%d",&mark);


  if(mark<=30)
  {
         printf("fail & very low mark\n");
  }

   else if(mark<=50)
    {
        printf("pass & better mark\n");
    }

  else if(mark<=70)
   {
        printf("pass & good mark\n");
   }
  else if(mark<=95)
   {
        printf("pass & very good mark\n");
   }
  else if(mark>100)
   {
        printf("please enter a correct mark");
   }
  else
   {
       printf("excelent mark");
   }
   getch();
}

Nested if condition The block of code following the else statement is executed as the condition present in the if statement is false. nested-if. Nested if statements means an if statement inside another if statement syntax if(condition-1) {     if (condition-2)        {         statement        }     else        {         statement block-2;        } } else  {    statementblock-3;  } Flow chart Example for nested if condition in [c-program] #include< stdio.h> void main() {   int a,b,c;   printf("Enter three number");   scanf("%d%d%d",&a,&b,&c);     if(a>b)       {         if(a>c)         ...

Switch statement  switch statement is an extension of if...else statement. This permits any number of branches. The general form is switch(expression) { case 1 statement block-1; break; case 2 statement block-2; break; .............. .............. .............. case n statement block-n; break; default  default statement; break; } next statement; the value of the expression will check with the case 1, case2,...casen if any case will matches then execute that case statement.then it moves to the next statement. flow diagram: Example program: #include<stdio.h> #include<conio.h> void main() { int number; clrscr(); printf("Enter your exam mark"); scanf("%d",&number); switch(number) { case 35: printf("low mark"); break; case 50: printf("better mark"); break; case 90: printf(...
