Remove space from char array (2 ways)

#include <stdio.h>

int main()
{
    const char* frase = "oi pessoal da vida !";
    char* dest = (char*) malloc (sizeof(frase)+1);

    int f=0,d=0;
    while(frase[f++] != '\0') {
        if(frase[f-1] != ' ')
            dest[d++] = frase[f-1];
    }

    print(dest);
    return 0;
}


//or
//not by me

#include <stdio.h>

void remove_space(char *d, const char *s){
    for(;*s;++s){
        if(*s != ' ')
            *d++ = *s;
    }
    *d = *s;
}

int main(){//DEMO
    char secuencia[] = "1 2 3 4 5 6 7 8 9";
    char temp[sizeof(secuencia)];
    remove_space(temp, secuencia);
    puts(temp);//123456789
    return 0;
