(C) - IF statement doesn't work

(sorry for my bad english) :)

I made a simple program that allows the user to add something in the array, or close the program.

#include <stdio.h>
#define MAXSIZE 100

enum boolean{FALSE, TRUE};

int main()
{
    char line[MAXSIZE], c, ch;
    int i;
    int state;

    int state = TRUE;
    while(state != FALSE){
        printf("1.Add something in the array\n2.Print out the contenent of the array\n3.Exit\n");
        ch = getchar();

        if(ch == '1'){
            system("cls");
            printf("Type\n");
            for(i = 0; i < MAXSIZE && (c = getchar()) != '\n'; i++){
                line[i] = c;
             }

        line[i] = '\0';
        }
        else if(c == '2'){
            system("cls");
            printf("Contenent of the array\n");
            for(i = 0; line[i] != '\0'; i++){
                printf("%c", line[i]);
            }
        }
        else if(c == '3'){
            system("cls");
            printf("End.");
            state = FALSE;
        }

    }

return 0;

}

Well, nothing works ! But if I use EOF instead of '\n', the program at least lets me add chars in the array. The program doesn't work even if i use the switch statement instead of the if.

I don't know what to do, please help Thank you. :)
