as you said, no other tutorial has explained this much detail ... thanks bro

[coolbuddy]

Thanks for this. There is no content on the internet explaining clearly why we need to clear the buffer.

[sainithyamsani]

In short...

Any input values are not stored directly into the ram or variable.
First, the input be placed in the buffer memory. From here, scanf function will read the data sequentially and then converts the char data into int type. After this only, the value is stored into the variable i.e. ram.

You can use fflush(stdin), after printf which will clear buffer and can intake the character

[marduktr]

Thank you for the clean explaination. Why do you not use fflush(stdin) function instead of typng getchar() function twice?My instructor told me that it was not a safe function but he didn't dive into.Hence, I am not convinced by the answer. I would be happy if you can explain.

Best,

I would type:

int age;
char gender;

printf("Please enter your age: ");
scanf("%d", %age);

printf("Please type your gender: ");
fflush(stdin);
gender=getchar();
printf("Your age is %d and your gender is %c ", age, gender)

return 0;

[harshraj_]

if after converting into age, the characters are removed, how and when is the data of buffer sent to stdin ?
