Ques:-14) Write a program to print all the ASCII values and their equivalent characters using a while loop. The ASCII values vary from 0 to 255.
#include<stdio.h>
#include<conio.h>
#include<dos.h>
void main()
{
int i=0;
clrscr();
printf("ASCII value are:");
while(i<=225)
{
printf("%d = %c \n\n",i,i);
i++;
delay(100);
}
getch();
}

Another Example
Below is a C program that prints all the ASCII values from 0 to 255 along with their equivalent characters using a while loop.
#include <stdio.h>
int main() {
int ascii_value = 0;
// Print header
printf("ASCII Value\tCharacter\n");
printf("--------------------------\n");
// Loop through ASCII values from 0 to 255
while (ascii_value <= 255) {
printf("%d\t\t%c\n", ascii_value, ascii_value);
ascii_value++;
}
return 0;
}
Explanation:
Include necessary header:
#include <stdio.h>for standard input/output functions.
Variable declaration:
int ascii_value = 0;– This variable is used to store the current ASCII value in the loop.
Printing the header:
printf("ASCII Value\tCharacter\n");andprintf("--------------------------\n");print the header for the output table.
While loop:
- The
whileloop runs as long asascii_valueis less than or equal to 255. - Inside the loop,
printf("%d\t\t%c\n", ascii_value, ascii_value);prints the current ASCII value and its corresponding character. ascii_value++;increments the ASCII value by 1 for the next iteration.
- The
End of the program:
- The
return 0;statement indicates that the program finished successfully.
- The
ASCII Value Character
