What is the Differences Between putw and putchar in C Programing Language
Putchar writes a single character to the console. Whereas putw is used to write an integer value into a file.
Putchar returns the int value of the character it wrote to the output console. Whereas putw returns zero on successful operation otherwise non-zero value is returned.
Putw requires a pointer to file but putchar doesn’t require a pointer.
Prototypes are as below:
int putw(int w,FILE *strm);
int putchar(int);Easily remember the differences using the table below:
| putw function in c | putchar function in c |
| Used to write an integer value into a file. | It writes single character to stdout. |
| Returns zero on successful operation otherwise non-zero value is returned. | It returns the int value of the character it wrote to the console. |
int putw(int w,FILE *strm); | int putchar(int); |
