I would really love your help with the following problem:
I want to get as an input from the user a maximum length of 30 chars string and check whether it contains an end of line.
This is what I tried to write so far:
int main(void) {
int i;
char* command = (char*)calloc(31, sizeof(char));
while (0 < 1) {
scanf("%s", command);
for (i = 0; i <= strlen(command); ++i) {
if (command[i] == '\n')
printf("here");
}
if (strcmp(command, "quit") == 0)
break;
}
The idea is to check whether the command given by the user as input is "legal" - that is of length < 31. when i run this code, it never prints "here" regardless of the length of input.
