adding __TIME__ macro to char malloc

**cable** · 09-29-2011

Code:


char *time=(char*)malloc(9*sizeof(char *));
	time=__TIME__; 
	for(i=0;i<9;i++);
		if(time[i]>='0' && time[i]<='9')
		printf("correct");

but it's not working... any help please?
the 'error message' its no print message
any help would be grateful
what i want is to get every number of the time for example if time is 20:22:23
i want to get a string 202223

Lose the semicolon lon line 3 ...

Don't typecast the return value of malloc() ... if your compiler complains about it's because it thinks it's compiling C++.

__TIME__ is a string literal. Your allocated memory leaks out when you assign the __TIME__ address to your pointer.

You could use:

Code:

const char* time = __TIME__;

or:

Code:

char* time = malloc(strlen(__TIME__) + 1);

strcpy(time, __TIME__);

i have made this change but a strange thing happens look
my new code and the output

Code:

char* time = malloc(strlen(__TIME__) + 1);
strcpy(time, __TIME__);
for(i=0;i<strlen(__TIME__) + 1;i++)
if(time[i]>='0' && time[i]<='9')
printf("%d\n",atoi(time+i));

output

Just try this.

Code:

int a, b, c;
char* time = malloc(strlen(_TIME__) + 1);
strcpy(time, _TIME__);
sscanf(time, "%02d:%02d:%02d", &a, &b, &c);
printf("%02d\n%02d\n%02d", a, b, c);

This would work to.

Code:

int i;
char* time = malloc(strlen(__TIME__) + 1);
strcpy(time, __TIME__);
for(i=0; i<strlen(__TIME__)-1; i++)
{
    if(time[i]==':')
    {
        time[i]='\n';
    }
}
    printf("%s", time);

Or even this

Code:

sscanf(__TIME__, "%02d:%02d:%02d", &a, &b, &c);
