C if-else Statement :

if-else :

if-else statement is used to execute a statement block or a single statement depending on the value of a condition.

Example 1 :

  1. /* Description: program to find biggest of two numbers */
  2. #include<stdio.h>
  3. #include<conio.h>
  4. main()
  5. {
  6. int a,b,big;
  7. //clrscr();
  8. printf("\n Enter two numbers:\n");
  9. scanf("%d %d",&a,&b);
  10. big=a;
  11. if(b>big)
  12. big=b;
  13. printf("\n Biggest number is %d",big);
  14. getch();
  15. }

Note : clrscr() It is predefined function in "conio.h" (console input output header file), by using this function we can clear the data from consol(Monitor), Here we skip this function( just remove // to you can use this function ).
getch() is a way to get a user inputted character (getch() andgetchar() are used to read a character from screen). It can be used to hold program execution.

Output 1 :

c language - program to find biggest of two numbers

Example 2 :

  1. /* Description: simple if-else example */
  2. #include<stdio.h>
  3. main()
  4. {
  5. int a;
  6. printf("\n Enter only number 1\n");
  7. scanf("%d",&a);
  8. if(a==1)
  9. {
  10. printf("You enter right number.");
  11. }
  12. else
  13. {
  14. printf("You press wrong number.");
  15. }
  16. getch();
  17. }

Output 2 :
