Thread: problem with chars and function call

Hello,I'm learning C and I've got a question. what is wrong with my code? I expect that the users enter sunny, cloudy, rainy and the program to pick the first letter. Then with that first letters fo to swit function and print.

Code:

#include <stdio.h>
#define TAMANIO 10
void swit(char st[TAMANIO]);
int main () {
    int i;
    char str[TAMANIO];


    printf("Enter your weather - sunny - cloudy- rainy: \n");
    for (i = 0;i < TAMANIO ;i++  ){
    scanf("%s",&str[i]);
    if (str[i] == EOF) {
    i = (TAMANIO -1);
    } //IF user enter eof breaks the for cycle.
    }
    swit(str[0]);
}
void swit(char st[TAMANIO]) {


    switch (st[0]) {
        case 's':
            printf("pick up your sunscreen: ");
        break;


        case 'c':
            printf("pick up your jacket");
        break;


        case 'r':
            printf("pick up your umbrella");
        break;


        default:
            printf("wrong weather! ");
        break;
    }//end swith
}
