if else control statement in c
`if` aur `else` C programming language mein conditional statements hote hain, jinke madhyam se aap program ko conditionally control kar sakte hain. Inka istemal aapke program mein decision-making aur control flow ko handle karne ke liye hota hai. Yahan `if` aur `else` statements ke basic syntax aur unka istemal ka ek example diya gaya hai:
**Syntax:**
```c
if (condition) {
// Code to be executed if the condition is true
} else {
// Code to be executed if the condition is false
}
```
- `if`: Yeh keyword ek condition define karta hai. Agar yeh condition true hoti hai, to `if` block ke andar ke code ko execute kiya jata hai.
- `else`: Agar `if` condition false hoti hai, to `else` block ke andar ke code ko execute kiya jata hai.
**Example:**
Yahan ek example hai jisme `if` aur `else` ka istemal kiya gaya hai:
```c
#include
int main() {
int age;
printf("Enter your age: ");
scanf("%d", &age);
if (age >= 18) {
printf("You are an adult.\n");
} else {
printf("You are a minor.\n");
}
return 0;
}
```
Is program mein user se age input liya jata hai. Fir `if`
statement check karta hai ki age 18 se badi hai ya nahi. Agar age 18 ya usse badi hai, to "You are an adult." print hota hai,
aur agar age 18 se choti hai, to "You are a minor." print hota hai.
`if` aur `else` statements ka istemal aapko program mein conditions ke adhar par control
flow ko handle karne mein madadgar hota hai. Aap multiple `if` aur `else` statements ka istemal karke complex decision-making logic bhi develop kar sakte hain.
