For my programming class I need to write a program that reads a ground number and a power, calculates, and then prints the answer on screen.
for this program the teacher makes me use pointers and different sub programs for the input output and calculation.
my code is:
/*Libraries*/
#include<stdio.h>
#include<conio.h>
/*Subprograms*/
void input(int *, int *);
void To_Decimal(int *, int *, int *);
void Output(int,int,int);
/*Main program*/
int main()
{
/*variables*/
char chAgain = 'y';
while(chAgain == 'y')
{
/*variables*/
int nGround = 0, nPower = 0, nDecimal = 1;
/*goto subprogram input*/
input(&nGround,&nPower);
/*check arguments*/
if(nGround < 10)
{
/*goto subprogram to decimal*/
To_Decimal(&nGround,&nPower,&nDecimal);
/*goto subprogram output*/
Output(nGround,nPower,nDecimal);
}
else
{
printf("\nThe ground number you have entered is 10 or a higher number");
}
printf("\nDo you want to run the program again? [y/n]: ");
chAgain = getche();
}
return 0;
}
/*subprogram input*/
void input(int *pGround, int *pPower)
{
printf("\nEnter a ground number below 10: ");
/*read the ground number*/
scanf("%d",pGround);
printf("\nEnter a Power: ");
/*read the power*/
scanf("%d",pPower);
}
/*subprogram to decimal*/
void To_Decimal(int *pGround, int *pPower, int *pDecimal)
{
/*do the math*/
int i;
for (i = 0; i < *pPower; i++)
{
*pDecimal *= *pGround;
}
}
/*subprogram output*/
void Ouput(int nGround, int nPower, int nDecimal)
{
printf("\nThe outcome of the groundnumber: %d and the power: %d is %d",nGround,nPower,nDecimal);
}
I'm getting 2 errors when I try to compile.
error LNK2019: unresolved external symbol "void __cdecl Output(int,int,int)" (?Output@@YAXHHH@Z) referenced in function _main
Error 5 error LNK1120: 1 unresolved externals
can someone please help me to solve them.
