I m new in c++ how to solve error:
 
  1. main.cpp: In function ‘int main()’:  
  2. main.cpp:25:47: error: invalid types ‘int[int]’ for array subscript  
  3. result[size]=add(num1[size],num2[size]);  
  4. ^  
  5. main.cpp:25:58: error: invalid types ‘int[int]’ for array subscript  
  6. result[size]=add(num1[size],num2[size]);  
  7. ^  
  8. main.cpp:25:59: error: ‘add’ was not declared in this scope  
  9. result[size]=add(num1[size],num2[size]);  
  10. ^  
  11. main.cpp:30:52: error: invalid types ‘int[int]’ for array subscript  
  12. result[size]=subtract(num1[size],num2[size]);  
  13. ^  
  14. main.cpp:30:63: error: invalid types ‘int[int]’ for array subscript  
  15. result[size]=subtract(num1[size],num2[size]);  
  16. ^  
  17. main.cpp:30:64: error: ‘subtract’ was not declared in this scope  
  18. result[size]=subtract(num1[size],num2[size]);  
  19. ^  
  20. main.cpp:34:52: error: invalid types ‘int[int]’ for array subscript  
  21. result[size]=multiply(num1[size],num2[size]);  
  22. ^

  24. result[size]=multiply(num1[size],num2[size]);

c++ programme:
 
 
  1. using namespace std;  
  2. #include   
  3.   
  4. int main()

  35.                     break;  
  36.                       
  37.                 case '/':  
  38.                     if(num2[size]==0)  
  39.                     {

  50.           
  51.                 default:  
  52.                     operation[size]= 0;   
  53.                     system("cls");  
  54.                     cout<<"PLEASE ENTER A VALID OPERATION.\n\n";  
  55.                     cout<<"First Number: "<
  56.                     cout<<"Second Number: "<
  57.                     cout<
  58.             }  
  59.         }  
  60.     while(!(operation[size]));     
  61. }
