c strings in an array problem
Hi,
How should I go about storing strings in an array without using the getc function? getc works but it's apparently not a good function to use. I tried getline, but I always get a segmentation fault when reading from the array. Thanks. getc line of code: int n; char names[10][31]; for( n=0; (n<MAX) && gets(names[n]); n++ ){ } |

Use fgets, lol.
fgets(stdin, 30, names[n]);

Use code tags.
