Programming in C

Variable-Length Character Strings
207
If s1, s2,and s3 are defined to be character arrays of appropriate sizes, execution of
the statement
scanf ("%s%s%s", s1, s2, s3);
with the line of text
micro computer system
results in the assignment of the string "micro" to s1, "computer" to s2,and "system"
to s3. If the following line of text is typed instead:
system expansion
it results in the assignment of the string "system" to s1,and "expansion" to s2.
Because no further characters appear on the line, the scanf function then waits for more
input to be entered from your terminal window.
In Program 10.5, scanf is used to read three character strings.

Reading Strings with scanf
// Program to illustrate the %s scanf format characters
#include
int main (void)
{
char s1[81], s2[81], s3[81];
printf ("Enter text:\n");
scanf ("%s%s%s", s1, s2, s3);
}
printf ("\ns1 = %s\ns2 = %s\ns3 = %s\n", s1, s2, s3);
return 0;
Program 10.5 Output
Enter text:
system expansion
bus
s1 = system
s2 = expansion
s3 = bus
