Thread: printing half a char array

well i fixed my problem
i used %.29s flag with printf to limit the number of chars printed and i removed that whole for loop and used

Code:

while (playtime[i]!=0)/* if playtime ==0 then there is no song there*/
	{
		mins = 0;/* tryint to make it obvious if convert method isnt working*/
		secs = 0;/* by initializeing mins and secs or each new song to 0*/
		convertSecondsToMinutes(&mins, &secs, playtime[i]);
		
		titles[i][(strlen(titles[i])-1)] = '\0'; /* this is how i found 
								the newline char and replace 
								it with null, then i just printed
								a newline at the end of my real 	
								printf statemnet*/
		
		if (select[i] == 1)
		{
			printf("*");/* indicates song is selected*/
		}
		else
		{
			printf(" ");/* holds place of * to keep spaceing same*/
		}
		printf("[%1d]%3d:%02d %.30s\n", i+1, mins, secs,  titles[i] );/* prints song info...*/
		i++;

i used strlen() to find the end of the string and i knew the new line char was the second from last beacuse the null is last and i replaced it with null

that didnt work as good as i hoped it would
this found the newline and replaced it with null

Code:

for(j=0; j<30; j++)
{
	if(titles[i][j]=='\n')
	{
		titles[i][j] = '\0';
	}
}
