can someone help me with this coding , actually I was ask to make a program about milling machine and my output is -Part machining time -Total energy consumption -total operation cost -by products or solid waste generation Estimated productivity per day

but i miss "total operation cost" , can u add it in my program, idk how to insert it.

here is my coding;

#include #include

int main() { int a,b,c,d,r,e,f,g,h,t,G,P,q; float y,I,J,k,l,n,m,z,j; float pI=3.142; printf("WELCOME TO MILLING MACHINE "); printf("PLEASE PUT YOUR PLATE ON THIS MACHINE "); printf("SPEED OF MACHINE "); printf("1mm to 2mm: 120mm/s "); printf("3mm to 7mm: 43.3mm/s "); printf("8mm to 10 mm: 18.77mm/s "); printf("PLEASE ENTER THE PART PARAMETERS "); printf("LENGTH OF WORKPIECES(mm): "); scanf("%d",&a); printf("WIDTH OF WORKPIECE(mm): "); scanf("%d",&b); printf("THICKNESS OF WORKPIECE(mm): "); scanf("%d",&c); printf("DISTANCE FROM EDGE TO CUT(mm): "); scanf("%d",&d); printf("HOLE RADIUS(mm): "); scanf("%f",&r); printf("LENGTH OF 1st CUT(mm): "); scanf("%d",&e); printf("DEPTH OF 1st CUT(mm): "); scanf("%d",&f); printf("LENGTH OF 2nd AND 3rd(mm): "); scanf("%d",&g); printf("DEPTH OF 2nd AND 3rd CUT(mm): "); printf("%d",&h); if(c<=3) { y= 3.142*pow(r,2); n=2*3.142*r/120; j=d+r+r; m=2*h; z=a-m; k=b-m; l=2*z+2*k; t=l/120+4*n; } else if(c<=7) { y=3.142*pow(r,2); n=2*3.142*r/43.3; j=d+r+r; m=2*h; z=a-m; k=b-m; l=2*z+2*k; t=l/43.3+4*n; } else if(c<=10) { n=2*3.142*r/18,77; j=d+r+r; m=2*h; z=a-m; k=b-m; l=2*z+2*k; t=l/18.77+4*n; } else { printf("ERROR "); printf("PLEASE TRY AGAIN "); } printf(" MACHINING TIME(s) : %d ",t); G=3.142*pow(r,2)*c; printf("SCRAP GENERATED(kg) : %d ",G); P=t/28800; printf("OUTPUT PER DAY : %d ",P); q=a*b*c-4*G; J=a*b*c/q; printf("MATERIAL EFFICIENCY : %f ",J); printf("ENERGY UTILIZATION(8HOURS) : 3KW"); return 0; }
