Expert's answer

#include <stdio.h>

int main(){

double summation;//variable for sum

double firstnumber;

double secondnumber;

//prompt user to enter first number

printf("Enter first number: ");

//read first number

scanf("%lf",&firstnumber);

//promt user to enter second number

printf("Enter second number: ");

//read second number

scanf("%lf",&secondnumber);

summation=firstnumber+secondnumber;//add

//the system must display the summation of the number

printf("The summation of the number = %.3f\n",summation);

system("PAUSE");//delay

return 0;

}

#include <stdlib.h>

int main(){

double summation;//variable for sum

double firstnumber;
