hi i am new to programming in c ,
and i wanne know how to compare 2 strings
one string should be true keyboard input "gets(a);
and the other string i wanne read from a .txt file with fgets(b,30,f)
if (strcmp(a,b)==0) dont work cause the value of strcmp is 1 ore -1
how to set it to 0 and see if the strings are equal ?
sorry for my bad english .
greetings GMK0000
See, gets and fgets work differently. The first ignores the newline character while the second adds it to the string. I suggest using fgets for both the console and file input. Like this:
Code:fgets(a, 30, stdin);
thanx for your reaction i am gonne try it out tonight
p.s.
you really devoted your life to program ? hahaha
if so let me add you as a friend
works perfectly thanx mate.
You really should forget that you've even heard of the gets() function. This function can never be safely used and has even been removed from the current C standard.
