Answer:
Written in C Language
#include <stdio.h>
int main() {
float temp;
printf("Temperature: ");
scanf("%f",&temp);
temp-=(temp + temp);
printf("%.6f", temp);
return 0;
}
Step-by-step explanation:
This line declares temp as float
float temp;
This line prompts user for input
printf("Temperature: ");
This line gets user input
scanf("%f",&temp);
This line negates the user input
temp-=(temp + temp);
This line prints out the required output with a - sign
printf("%.6f", temp);
