If Else condition in C Language:
(1) If Else statement allows us to write two alternative paths and the control condition determines which path gets executed. In an if-else statement, only the code associated with if (i.e. statement-1) or the code associated with else (i.e. statement-2) executes, never both.
(2) Sample C language code and its output, as shown:
| #include <stdio.h> #include <conio.h> intmain() { int x; int y; x = 5; y = 7; // If else in C Language if (x > y) { printf(“x is greater than y\n”); } else { printf(“x is less than y\n”); } // If else if in C Language x = 10; y = 10; if (x > y) { printf(“x is greater than y\n”); } else if (x = y) { printf(“x is equal to y\n”); } else { printf(“x is less than y\n”); } getch(); return 0; } |
(3) After that go to the “Build” menu and select the “Build” option for publishing the code as shown.
(4) After building the code, press the “Run” button, as shown.
(5) After pressing the “run” button, the output screen is opened, as shown.
If Else Syntax:
| if (condition) { // block of code to be executed if the condition is true } else { // block of code to be executed if the condition is false } |
If Else If Syntax:
| if (condition1) { // block of code to be executed if condition1 is true } else if (condition2) { // block of code to be executed if the condition1 is false and condition2 is true } else { // block of code to be executed if the condition1 is false and condition2 is false } |
