Question

This is not needed, but a curiosity with that program. Would you have any clue as how to reduce the fractions tolowest terms with a simple math problem? I have been going overthat one in my head, thinking that it would take at least a fewsteps and some if statements, which honestly, is not worth doing atthis point.

x.P5lor="red">please rate - thanks this is added to this mornings post. note the move of the output, from 4 times in the switch, to once outside the switch make a decision about negative numerators. because right now   -1/2 - #include #include #include #include using namespace std; //prototype of the functions bool getnum(int&); int gcd(int,int); char menu(); void addFractions( int a1, int b1, int a2, int b2, int & num, int & den ); void subtractFractions( int a1, int b1, int a2, int b2, int & num, int & den ); void multiplyFractions( int a1, int b1, int a2, int b2, int & num, int & den ); void divideFractions( int a1, int b1, int a2, int b2, int & num, int & den ); int main() // function main begins program execution { int a1, b1, a2, b2, num, den, exit,factor; bool good1=false,good2=false,num1found=false,num2found=false,inputerror; char ch = menu(); while (ch!='X') { //Try block checks for input validation //throws if exception occured do { try      {if(!good1)       {if(!num1found)           {// prompt and read the input from the user           cout > a1;           inputerror=getnum(a1);           if(inputerror)                { string s="valid number not entered";                 throw s;                 }           num1found=true;           }          // prompt and read the input from the user      cout > b1;     inputerror=getnum(b1);           if(inputerror)                { string s="valid number not entered";                 throw s;                 }      // validate the denominator      if ( b1 == 0 )         throw b1;      else if (b1 a2;           inputerror=getnum(a2);           if(inputerror)                { string s="valid number not entered";                 throw s;                 }           num2found=true;           }      // prompt and read input from the user      cout > b2;      inputerror=getnum(b2);           if(inputerror)                { string s="valid number not entered";                 throw s;                 }         // validate the denominator      if ( b2 == 0 )         throw b2;      else if (b2
