Variable 'l1' is uninitialized when used here

The error message "Variable 'l1' is uninitialized when used here" indicates that you are using a variable called 'l1' without initializing it with a value beforehand. In C, it is important to initialize variables before using them, as they can contain random or garbage values if not explicitly initialized.
To fix this error, you need to initialize the variable 'l1' with a value before using it. Here's an example:
```c
#include <stdio.h>
int main() {
int l1 = 10; // Initialize 'l1' with a value
// Rest of your code using 'l1'
printf("The value of l1 is: %d\n", l1);
return 0;
}
```
In the above example, the variable 'l1' is initialized with a value of 10 before using it in the printf statement. This ensures that 'l1' has a valid value when it is accessed.
Remember to always initialize variables with appropriate values before using them to avoid such errors.
