Sprintf function clarification

[CodingLearner]

If i have a sprintf function like

void send(void)
{
char buffer[10];
int value=-10;
sprintf(buffer,"%d",value);
}

so does buffer contain data like this?
buffer[0] = '-'; // ascii value of -
buffer[1]='1'; // ascii value of 1
buffer[2] ='0'; // ascii value of 0
Please advise.
