I am getting an unexpected error that does not make sense to me

line 3: syntax error near unexpected token '('
line 3: 'int main () {'

#include <stdio.h>

int main () {
    int x;
    char c;

    printf("1. Shape Printern");
    printf("2. Circular Charsn");
    printf("3. Factorsn");
    printf("4. Exitn");
    printf("What would you Like to do? n");
    scanf("%d %c" , &x, &c);

    return 0;
}
