Question

C Programming

I have this cost estimation program, but I want to add to it more functions to be more accurate and more useful. I want to add to the program an array and a loop that can help me with the materials that can be use to the building, as ceramic, wood and concrete and extra functions.

float wid,len,yrs;

strings can't be compared directly so use strcmp method from header file string.h

code

#include <stdio.h>
#include <string.h>

int main(void)
{
//for taking more than one building value
char choice;
do{
float wid,len,yrs;
int metersq = 2000;
int floors,rooms,win,doors,restrooms,umet;
char floortype[20];
char ti[20];

//chars for comparison
char *w="wood",*normaltime = "normaltime";
int woodfloor = 25;
int ceramic = 15;
int doorcost = 200 , metaldoor = 150;
int windowcost = 100;
float materialcost = 131.0371;
int paintcost = 100;
int arcitectcost = 3000;
int restroomcost = 2000;
int costengineer = 6000;
int costeachworker = 4000;
int totalrooms ,totalcost, totalwin , totalmaterial,totalmaterialcost,totalarchitect, totaldoors ,totalarchitectcost, totalrestroom , totalcostrest , totalcostworker , totalcostfloor, totalwincost, totalnoengineer, totalengineercost;
printf("How long is your width and length of your building?\n");
scanf("%f %f",&wid,&len);
printf("How many floors will the building will have?\n");
scanf("%d",&floors);
printf("How many rooms per floor?\n");
scanf("%d",&rooms);
printf("How many windows per floor?\n");
scanf("%d",&win);
printf("How many doors per floor?");
scanf("%d",&doors);
printf("How many years would you like to wait for the project? \n");
scanf("%f",&yrs);
printf("Which floor material would you like to use on your biulding? (wood, ceramic or concrete)\n");
scanf("%s",floortype);//read a string using %s itself , no & is required to read a string
printf("How soon do you want your building? normal time or faster? Enter normaltime or faster \n");
scanf("%s",ti);//read a string using %s itself , no & is required to read a string
printf("How many restrooms per floor?\n");
scanf("%d",&restrooms);

totalrooms = floors*rooms;
totalwin = floors*win;
totaldoors = doors + totalrooms;
totalrestroom = floors*restrooms;
totalcostrest = totalrestroom*restroomcost;
totalcostworker = yrs*costeachworker;
if(strcmp(ti,normaltime)==0)
{
totalcostworker = totalcostworker*1;
}
else
{
totalcostworker = 2*totalcostworker;
}
if(strcmp(floortype,w)==0)
{
totalcostfloor = 25*floors;
}
else
{
totalcostfloor = 15*floors;
}
totalwincost = totalwin*windowcost;
  
totalnoengineer = floors*2;
totalengineercost = totalnoengineer *costengineer;
  
totalarchitect = floors*1;
totalarchitectcost = totalarchitect*arcitectcost;
totalmaterial = wid*len*floors;
totalmaterialcost = totalmaterial*materialcost;
totalcost = totalmaterialcost+totalarchitectcost+ totalwincost+ totalcostfloor+totalcostworker+totalcost;
printf("the total cost is %d dollars",totalcost);
printf("enter q to quit");

//space to read character otherwise it reads blank space
scanf("%c",&choice);
}while(choice!='q');
return 0;
}

output

How long is your width and length of your building? How many floors will the building will have? How many rooms per floor? How many windows per floor? How many doors How many years would you like to wait for the project? 6 Which floor material would you like to use on your biulding? (vw ood, ceramic or concrete) wood How soon do you want your building? normal time or faster? Ente r normaltime or faster faster How many restrooms per floor? per floor?1 the total cost is 65537 dollarsenter q to quit, c to continueq
