What is wrong with my code? i keep getting the "Invalid operand to binary" on line "var1=var1-1;" please help me solve this. this is a very simple code...it's to count out the prime numbers... take a look and tell me what is wrong...thankz #include #include int main(){int numofout;int var1, var2, var3, var4;int count1=3;int count2=3;printf("\n\t\tEnter the number of prime numbers\n\t\tyou wish to find (number > 3):");scanf("%i", &numofout);while(numofout 3! "); scanf("%i", &numofout);}printf("\n\n\t\t1 is the 1st prime number.\n\t\t2 is the 2nd prime number.\n\t\t3 is the 3rd prime number.\n");do{count1=count1+1; do { count2=count2+1; var1=count2; do { var1=var1-1; var2=count2 % var1; } while(var2!=0

Try changing "var1=var1-1;" to "var1-=1;" and see if the error still occurs. I'm not sure if it's only an error on the way you posted the code to the forum, but your last line lacked a closing parentheses.
