How to solve/finish this string exercise?

Question

Code I’ve made so far:

int main()
{
    char string[100], c;
    int removidas;
    
    fgets(string,100,stdin);
    
    scanf("%c", &c);

    removidas = funcao(string, c);
    
    printf("Numero de remocoes: %d\n", removidas);
    printf("String sem o caractere '%c': %s", c, string);

    
    return 0;
}

Thanks to those who help!!
