Question: How do I print a floating-point number with higher precision say 23.34568734 with only precision up to two decimal places?
Answer: This can be achieved through the use of suppression char '*' in the format string of printf( ) as shown in the following program.main( ) { int i = 2 ; float f = 23.34568734 ; printf ( "%.*f", i, f ) ; } The output of the above program would be 23.35. |

{ int i = 0 , a[3] ;
a[i] = i++;
printf ("%d",a[i]) ;
} - Why doesn't the following code give the desired result?
int x = 3000, y = 2000 ;
long int z = x * y ; - Why doesn't the following statement work?
char str[ ] = "Hello" ;
strcat ( str, '!' ) ; - How do I know how many elements an array can hold?
