1)why must type after #include? 2)why must place a % before conversion specifier (eg: %d ) 3)can u explain the "%4d" the output is " 1 ", what is the meaning of 4? 4)why there is a . before c.s (eg: %.11s) 5)why there is a - before c.s (eg: %-10s)

correction for the command #include main( ) { printf(“%u\n%x\n%X\n%e\n%E\n%f\n%g\n%G\n%c\n%s\n%4d\n %4d\n%.3f\n%.11s\n%10s\n%-10s\n”, 455,455,455,455,1234567.89,1234567.89,1234567.89,1234567.89, ‘A’, “This is a string”,1,12345,123.94536,“Happy Birthday”, “Hello” , “Hello”); }
