When we want toprint the value for any variablewith any datatype, we have to use aformat specifierin theprintf()statement. What happens if the value is out of Range? Well, if you try to assign a value to any datatype which is more than the allowed range of value, then the C langu...
After we solved this issue in the previous code, we have to deal with theprintfstatement that uses%sspecifier to print the buffer contents. Note that there is no guarantee that the last character of the input string is a null byte, so theprintfcall would not know where to stop if the ...
Extract characters from the input string and convert the character in hexadecimal format using%02Xformat specifier,%02Xgives 0 padded two bytes hexadecimal value of any value (likeint,char). Add these two bytes (characters) which is a hex value of an ASCII character to the output string. ...
The usage of the incorrect conversion specifier,%d, with an object of the typechar, results in an illogical outcome and triggers undefined behavior. To input a string, it is necessary to declare a character array, such as an example. char word[10]; and callscanflike scanf("%9s", word)...
value is: 44 Here the vale will be 44 Why? unsigned charstore only 8 bits data into the memory, when the value is greater than only first 8 bits will be stored, see the given image. In this image 8 bits value is: 0010 1100 which is equivalent to 44. ...
When it comes to printing character arrays, the%sspecifier inprintfplays a crucial role. A character array in C is essentially a sequence of characters stored in memory. While it shares a structure similar to C-style strings, character arrays don’t always end with the null character'\0'. ...
In this chapter we will learn all the functions used on strings in C - gets(), fgets(), getline(), getdelim(), getchar(), puts(), putchar(), strlen() in C language.

There is no run-time error checking to detect if a format specifier isused for which support is not included. The --printf_support optionprecedes the --run_linker option, and must be used when performingthe final link. Joseph Raslavsky 11 年多前 in reply to Dr.No Expert 1620 points ...
