طلب: حل الـ Homework الثاني لـ ICS 103

طيب رقم الكورس وحط السؤال علشان أقدر أساعدك.

 

Q1. [Points: 20] [To be done after covering Loops ] Question#5 on page#307 of your textbook: “Problem Solving and Program Design in C”, 6th Edition, with the additional requirement that your program must be interactive and it must check for input validity [Check only whether the number is negative or not. Don’t check the number of digits]. The program must loop, displaying an error message as long as the input integer is negative.
Sample runs of the program:


Q2. [Points: 20] [To be done after covering Loops and Data Files] Question#9 on page#307 of your textbook: “Problem Solving and Program Design in C”, 6th Edition; but use the following formula:

[ P + { (an^2) / (V^2) } ] (V-bn) = nRT
Also: note that in the sample run in the textbook, the Quantity of carbon dioxide (moles) is not 0.02 but 20
Sample run of the program:

 
The contents of your output file should be:

السؤال الثالث لكن القانون كتبت
خرابيط من عندي

#include<stdio.h>
#include<stdlib.h>
#define a 3.592
#define b 0.0427
#define R 0.08206
int main ()
{
double n, T, v1, v2, p, inc, v;
FILE *out;
out= fopen("results.txt", "w");
printf("Enter quantity of carbon :\n ");
scanf("%lf" , &n);
printf("Enter tempreture :\n ");
scanf("%lf" , &T);
printf("Enter Initial volume :\n ");
scanf("%lf" , &v1);
printf("Enter final volume :\n ");
scanf("%lf" , &v2);
printf("Enter volume increment :\n ");
scanf("%lf" , &inc);

fprintf(out, "%f of carbon dioxide at %f kelvin \n", n, T);
fprintf(out, "Volume \t \t Pressure \n");

for (v= v1; v<=v2; v= v+inc)
{

p= (n*R*T)/v;

fprintf(out, "%f \t \t %f \n", v, p);

}

fclose(out);

printf("Data succsesfully written to results.txt \n ");

system("pause");
}

 

لو تكتبون لي الــــ p وش تساوي أحولها لكم على أساس متغيراتي
