Maybe you can try to use "%s" to stand for format string. And also you need to define "n" by "char n[number]". Following is a demo which you need input a string and then it will return a sentence ,you can try to run.

#include<stdio.h>
int main()
{
char n[8] ;
printf("Please put in your name:");
scanf("%s",&n);
printf("Nice to meet you,%s!\n",n);
return 0;
}
