Nested if statement not working
hello friends
i am new to this forum
i am having some problem with nested if statement
when i run this code after enter age ,enter gender nothing shows on screen and program ends thereCode:#include <stdio.h>#include <stdlib.h> int main() { int age; char gen; printf("Enter your age : \n"); scanf("%d",&age); printf("Whats your gender m/f : \n"); scanf(" %c ",&gen); if (age >= 18){ printf("enter this website"); if (gen == 'm'){ printf("dude"); } } return 0; }
Just before the return 0, do this
It will catch your code before closingCode:putchar();
hello it shows error
He probably meant getchar(), not putchar()
Also, the trailing space after %c in the second scanf is going to mess you about as well.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Sorry, I did mean "getchar"
hello still no luck
Try putting a newline at the end "dude", or adding...
after your last printf to flush the output bufferCode:fflush(stdout);

you meant this?
this also doesn't print anything after age and gender is entered
Change this:
to this:Code:scanf(" %c ",&gen);
Notice I removed the trailing space in the format string.Code:scanf(" %c", &gen);

oh it worked! thanks...
now it works without these lines
but does c have space issues ?Code:getchar(); fflush(stdout);

The trailing space in the format string matches whitespace, so the issue is that you then need to have say, a trailing space in your input for it to be matched, otherwise your program would keep waiting for input to match. This is why it looked like nothing happened: your program was waiting for more input. Note that Salem mentioned this in post #4.
