Solution:
/* Read characters from the standard input/file and replace each character by the next character in the ASCII sequence. E.g., replace 'a' by 'b', 'z' by 'a'. */
#include<stdio.h>
int main()
{
int b;
char a;
printf("Enter the character");
scanf("%c",&a); // Machine reads the character
b=a; //b gets the ASCII value of the read character
//printf("the value of b is %d", b);
if(b>=97 && b<122)
{
b++; // ASCII value incremented
//printf("the next character's ASCII value is %d \n",b);
printf("the character is %c \n", b);
}
else if(b==122)
{
printf("the character is a");
}
return(0);
}
