Question

Language is C programming

Student ID should be 8 numbers long.

create a program to read your student ID number and store it in an array.

Input can not be hard wired, I have to be able to input my number
Then change the first number to a letter. If the same number repeats in other parts of your student ID, you must change that number to a letter as well.
print original array and modified array as your output.

Number to letter correspondence; 1=a, 2=b, 3=c, 4=d,5=e,6=f,7=g,8=h,9=i,0=j
i.e. if student id is 123583021
then outuput should look something like this
original = 123583021
modified = a2358302a (if you are really good is would be a2358302A)

CODE:

#include<stdio.h>
#include<stdlib.h>
int main(){
   char c[100];//array size
   scanf("%s",&c);//taking input from the user
   char s[100];//temperory array for storing the result
   int i;//variable for iterations in the loop
   int x=c[0];//variable that stores the first letter of the string
   for(i=0;i<sizeof(c);i++){//loop traversing entire string
       s[i]=c[i];//for copying letters to s i.e. Modified string
          
           if(s[i]==x){//checking modified string's first letter      
               if(x=='0'){//checks if the first letter is 0
                   s[i]='j';// if x=0, it prints j in the place of 0
               }
               else{
                   s[i]=(97+(x-49));//prints the modified string with the letters as per the output required
               }
           }  
   }
   printf("Original string:%s\n",c);
   printf("Modified string:%s",s);
}
