What is alternative of cin.ignore(); (used in C++) in C

Question

#include <stdio.h>

int main()
{
char ch,s[100],sen[200];

scanf("%c",&ch);//to input a character
scanf("%s",&s);//to input a string
gets(sen);//to input a sentence

printf("%c\n",ch);//to print character
printf("%s\n",s);//to print string
printf("%s",sen);//to print sentence

return 0;
}

In this Code memory of sen remains empty
i.e value inputed for sen is not being stored in it.

So what can be done to store it.
As scanf("%s", &sen); terminates on pressing space or enter

Thanks for your review Omkar
But the space after format specifier also terminates as the space appears.

I think I found an Alerternative of cin.ignore() in C

Nice solution.
However using space will also work.
You may have misplaced space.
You should give space between ending quote and 's' of format specifier

scanf("%s ",s);
//one more thing that you don't need a & because array name itself is pointer to first element.

There is no alternative for cin.ignore(); in C according to SO discussion:
https://stackoverflow.com/questions/53037333/whats-the-equivalent-of-cin-ignore-in-c

But using a space after format specifier will solve the problem.
scanf("%s ",s);// see the space after format specifier
