First of all, scanf() with format "%s" goes until first whitespace. It cannot read in "a string with spaces"; that would produce just "a". Second, you have a beginner's mistake in there: scanf("%s",&name); "name" is already a pointer, why are you the address of the pointer? No, you can’t. First of all, scanf() with format “%s” goes until first whitespace. It cannot read in “a string with spaces”; that would produce just “a”.

Second, you have a beginner’s mistake in there:

scanf(“%s”,&name);

“name” is already a pointer, why are you the address of the pointer?

Maybe you meant: while (!strcmp(fgets(text, sizeof(text), stdin), "[^n]"); althought I have no idea what you meant by that. You can’t compare C strings like that. Maybe you meant:

while (!strcmp(fgets(text, sizeof(text), stdin), “[^n]“);

althought I have no idea what you meant by that.

"); scanf("%s",&name); printf("Hello, %s. How are you?\n",name); return(0); } Same result. Or, we can just use

#include
int main()

scanf(“%s”,&name);
