Question

1. Write a main function and subfunctions in c language to compute the amount of steel and concrete required for the construction of a series of cooling tanks for a power plant. The dimensions of each tank (length l, width w, and height h are the input to the main program. The wall thickness is tw and the floor thickness is tf. The ratio of steel to concrete is 1:4.
   1. A function to compute the amount of steel required to construct each tank
   2. A function to compute the amount of concrete required to construct each tank
   3. A function to print the amount of steel and amount of concrete for each tank

Answer 1

#include"stdio.h"

/* calculation steel as volume */

float steelNeed(float a,float b,float c,float x,float y){
   float inner=a*b*c;/* internal volume */
   float outer=(a+2*x)*(b+2*x)*(c+2*y);/* external volume */
   float calculation=(outer-inner)/5.0;/* volume of steel */
  
   return(calculation);
}

/* calculation concrete as volume */

float concreteNeed(float a,float b,float c,float x,float y){
   float inner=a*b*c;/* internal volume */
   float outer=(a+2*x)*(b+2*x)*(c+2*y);/* external volume */
   float calculation=((outer-inner)*4.0)/5.0;/* volume of concrete */
  
   return(calculation);
}

/* print both calculation */

void print(float a,float b,float c,float x,float y){
   printf("\nSteel required fo a tank is %.5f m^3",steelNeed(a,b,c,x,y));
   printf("\nConcrete required fo a tank is %.5f m^3",concreteNeed(a,b,c,x,y));
}

/* main function start */
void main(){
   float l,w,h;
   float tw,tf;
  
   /* user inputs */
  
   printf("Enter the length (m) : ");
   scanf("%f",&l);
   printf("Enter the width (m) : ");
   scanf("%f",&w);
   printf("Enter the height (m) : ");
   scanf("%f",&h);
   printf("Enter the wall thickness (m) : ");
   scanf("%f",&tw);
   printf("Enter the floor thickness (m) : ");
   scanf("%f",&tf);
  
   /* print the result */
   print(l,w,h,tw,tf);
}
