Thread: Removing an array in an element?

Hi, i was wondering if there is a way to remove the element of an array. For example, in the following code i am using the one array to temporarily store multiple sets of data. The problem is that if the previous string was longer, it appends the current string. Each string is separated by commas.

Code:

for (x=0,j=0;x<i;++x) {
		
		if (line[x]!=',') {
			tmpNum[j]=line[x];
			++j;
		}else {
			printf("%s\n",tmpNum);
			j=0;              //this is where i "reset the array"
		}
}

so if i had the string "123", and the next string was "ab", the resulting output would be "ab3". Is there any way for me to remove the trailing characters? I know i can use a for loop and the length of each string to omit the unwanted characters but that's not my question.

You can use the bzero function to nullify a string, then when you write to the string again, you won't have any leftover data.
