    gotta love linker errors

    I get the following linker errors:

    Code:
        umneg.obj : error LNK2001: unresolved external symbol "int __cdecl num_neg(int * const,int)" (?num_neg@@YAHQAHH@Z)
    Debug/numneg.exe : fatal error LNK1120: 1 unresolved externals
    Any help would be greatly appreciated.

    Code:
    #include <iostream>
    using namespace std;
    int num_neg(int a[],int size );//prototype
    int main()
    {
    
     
     const int size=10;
    int a[size]={1,2,3,-4,5,-6,7,8,9,10};
    
    
     cout<<num_neg(a,size);//call
    
      return 0;
    
    }
    
    
     int pos(int a[], int size) //return number of negative values in array
     {
        int n=0;
    	 for(int i=0;i<size;i++){
             if((a[i]<0))
    	         n++;
    	  
    	                                   }
    	 
    	    return n;
    
    
    	 
    		   
    		
     }

    Just so you know, your function names don't match.

    The linker error is saying that you are calling a function named num_neg() but it can not find where that function is defined.
