New things learned from C

getchar() - probably i don't know that we can get char using this function also you can use this to capture newline character
       
        char sample;
        sample=getchar();

using scanf statement to get input in different way

input: 12-02-2017
scanf("%d-%d-%d",&day,&month,&year);

you can round digit using normal decimal notation
float a=109.7589;
printf("%.2f",a);

o/p:
109.76 // the last number is increamented by one


printing the " using printf using

printf(" \" ");
