discuss format specifiers in c code example
Example 1: what are format specifiers
it is used during taking input and out put
Int ("%d"):
Long ("%ld"):
Char ("%c"):
Float ("%f"):
Double ("%lf")
example:
char ch = 'd';
double d = 234.432;
printf("%c %lf", ch, d);
char ch;
double d;
scanf("%c %lf", &ch, &d);
Example 2: printf format specifiers c
/* printf example in C */
#include
int main()
{
printf ("Characters: %c %c \n", 'a', 65);
printf ("Decimals: %d %ld\n", 1977, 650000L);
printf ("Preceding with blanks: %10d \n", 1977);
printf ("Preceding with zeros: %010d \n", 1977);
printf ("Some different radices: %d %x %o %#x %#o \n", 100, 100, 100, 100, 100);
printf ("floats: %4.2f %+.0e %E \n", 3.1416, 3.1416, 3.1416);
printf ("Width trick: %*d \n", 5, 10);
printf ("%s \n", "A string");
return 0;
}
