Question

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);
}

Answer 2

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.
