There is a bug in RPN generator

3+4*2/(1-5)^2 -> 342*15-2^/+
if we put 3+ at the end…
4*2/(1-5)^2+3 -> 42*15-2^3+/ must be 42*15-2^/3+

to correct this bug change precedence detection part…

if(prec(infix[i]) <= prec(stack[tos-1])) {
temp=pop();
printf("\n the poped element is :%c",temp);
output[j++]=temp;
push(infix[i]);
printf("\n The pushed element is :%c",infix[i]);
show();
}

if(prec(infix[i]) <= prec(stack[tos-1])) {
while (prec(infix[i]) <= prec(stack[tos-1])) {
temp=pop();
printf("\n the poped element is :%c",temp);
output[j++]=temp;
}
push(infix[i]);
printf("\n The pushed element is :%c",infix[i]);
show();
}
