如何从 ASCII 数字中获取字符

Question

Hello. Im reading file using FILE and reading that using fgetc to read that.

fgetc function returns me int value of my chars in ASCII.

Now i want to print that data in char values.

How to convert my ascii numbers to chars?

Answer 1

You most likely don't need any conversion. If the native character set on your system is ASCII (which is the most common) then no conversion is needed. 'A' == 65 etc.

That means to print a character you just print it, with eg putchar or printf or any other function that allows you to print characters.

Answer 2

int x = 48;
printf("%c", x);

it will print 0, also you can do this

int x = 48;
char xx = (char)x;

Answer 3

Specify format as for a char, like so:

printf("%c", number);

printf("%c", 65); // A

Answer 4

#include <stdio.h>

int main()
{
int i;
for (i=97; i <=200 ; i++)
{
    printf("%d  %c,\t",i,i);
};
return 0;}

This will give you the whole chart upto 200.
