Consider following 2 codes inside main function.👇👇👇 why output is different in both the cases????

char arr[50],ch; scanf("%s",arr); scanf ("%c",&ch); printf("%s %c",arr,ch); or char arr[50],ch; scanf("%s %c",arr,&ch); printf("%s %c",arr,ch); Output of 1st is = arr Output of 2nd is=arr ch

char arr[50],ch; scanf("%s",arr); scanf ("%c",&ch); //here the remaining \n new line character is assigned to ch. How to avoid this: char arr[50],ch; scanf("%s\n",arr); scanf ("%c",&ch); That should be equivalent to your second code.

This is one of the many problems with scanf(). You should avoid the scanf() functions whenever you can, and use fgets() and getchar() instead.

due to white space in the buffer memory. Second scanf scans the white space and prints the whitespace. char arr[50],ch; scanf("%s",arr); scanf(" %c",&ch); printf("%s %c",arr,ch); Will work like second one because space before %c will skip the white space in buffer memory
