What does this C code do?
int k = -10;
int Temp;
while(k < 41){
Temp = k * 9/5 + 32;
k++;
printf(“Temp: %f \n”, Temp);
}
This C code converts temperatures from Celsius to Fahrenheit using a while loop.
The code first declares an integer variable "k" and initializes it to -10. It also declares an integer variable "Temp" without initializing it.
Then, the while loop runs as long as the variable "k" is less than 41. Inside the loop, the current value of "k" is multiplied by 9/5 and then added by 32 to convert it from Celsius to Fahrenheit. The result is stored in the variable "Temp".
After that, the value of "k" is incremented by 1 using the post-increment operator "k++".
Finally, using the printf function, the converted temperature "Temp" is printed in the format "Temp: %f", followed by a newline character.

The given C code is a loop that converts temperatures from Celsius to Fahrenheit.
Here is a step-by-step breakdown of what the code does:
1. It initializes an integer variable `k` with a value of -10.
2. It declares an integer variable `Temp` without initializing it.
3. It starts a `while` loop that will execute as long as `k` is less than 41.
4. Inside the loop, it calculates the Fahrenheit temperature by using the formula `Temp = k * 9/5 + 32`.
5. Then, it increments the value of `k` by 1 using the `k++` statement.
6. Lastly, it uses the `printf` function to print the converted temperature value `Temp` as a floating-point number with the message "Temp: ".
The loop will continue to iterate, adding 1 to `k` in each iteration, until `k` is no longer less than 41. The temperature values will be printed for each iteration.
This C code is a program that converts temperature values from Celsius to Fahrenheit.
Here's a step-by-step breakdown of how the program works:
1. Declare and initialize two variables:
- `k` is an integer variable initialized with the value -10.
- `Temp` is an integer variable that will store the converted temperature.
2. Enter a `while` loop that continues as long as the value of `k` is less than 41.
3. Within the loop:
- Calculate the Fahrenheit temperature value using the formula `(Celsius * 9/5) + 32`.
- Assign the result to the `Temp` variable.
- Increment the value of `k` by 1 using the post-increment operator (`k++`).
- Print the value of `Temp` using the `printf` function, with a format specifier `%f` to represent a floating-point number and a newline character `\n` for formatting.
4. Repeat steps 3 and 4 until the condition `k < 41` becomes false.
The program will output a series of Fahrenheit temperature values, starting from -10°C and incrementing by 1°C until it reaches 40°C.
