is there an any way to discard '\n'?

buffer, c, string

Solution

If you want to discard the `\n`:

char buf[0x1000];
fgets(buf, sizeof(buf), stdin);
char *p = strchr(buf, '\n');
if (p) *p = 0;

Problem

I am trying to to record response by the user(using `getchar()`). I am having issues with `'\n'` sticking in buffer. If I use `fgets(char* buf, .. , ..)`, `'\n'` again goes into `buf` and you have to include `'\n'` at the end of the test string. when using string.h functions (like `strcmp()`). Is there any clean way of writing code for such purposes. ``` #include<stdio.h> #include<string.h> int main() { char buf[100]; fgets(buf, 3, stdin); puts(buf); int i = strcmp("p\n", buf); printf("%d", i); //if (!strcmp("CLock to random\n", buf)) //{ //puts("sucess"); //} char c; c = getchar(); putchar(c); return 0; } ``` Now I want to record response(single character 'p'). If I use getchar(), in place of fgets(), program skips second getchar()( c = '\n'). If I use the current code, i have to include \n in strcmp() every time.
