Convert Uppercase Letters to Lowercase

Code

#include <stdio.h>
#include <stdint.h>
#include <string.h>
void to_lowercase(char *str) {
    int len=strlen(str);
    for(int i=0;i<len;i++)
    {
        if(str[i] >= 65 && str[i] <= 90)
        {
            str[i] = str[i] + 32;
        }
    }
}

int main() {
    char str[101];
    fgets(str, sizeof(str), stdin);

    // Remove newline
    uint8_t i = 0;
    while (str[i]) {
        if (str[i] == '\n') {
            str[i] = '\0';
            break;
        }
        i++;
    }

    to_lowercase(str);
    printf("%s", str);
    return 0;
}
