[Solved] Garbage values are getting assigned


Both global variables op and result need to be reset for each iteration of while loop.

while(arr_value[vali]!=1000)
{   
    //Set global x value
    x=arr_value[vali];
    //Solve expression 
    //Print result
    solveExpression(expression,80,x) ;  
    printf("\n result %d\n", result);       
    //Next Value        
    vali++; 
    result=0;
    op='\0'; // add this line to reset global variable
}
