Question : Clearing The Input Buffer In C/C++
Answered by : travinth-dayalaeaswaran
// C Code to explain why not
// clearing the input buffer
// causes undesired outputs
#include<stdio.h>
int main()
{
char str[80], ch;
// Scan input from user -
// GeeksforGeeks for example
scanf("%s", str);
// Scan character from user-
// 'a' for example
ch = getchar();
// Printing character array,
// prints “GeeksforGeeks”)
printf("%s\n", str);
// This does not print
// character 'a'
printf("%c", ch);
return 0;
