Write a program for a 5 digit no to print a new number by adding one to each of its digits

void main()
{
float a,b,c,d,e,t,s;
int a1,b1,c1,d1,e1,a2,b2,c2,d2,e2;
printf("\nInput a 5 digit number");
scanf("%f",&t);

a=t/10000.0;
a1=a;
b=(t-(a1*10000.0))/1000;
b1=b;
c=(t-(a1*10000.0)-(b1*1000))/100;
c1=c;
d=(t-(a1*10000.0)-(b1*1000)-(c1*100))/10;
d1=d;
e=(t-(a1*10000.0)-(b1*1000)-(c1*100)-(d1*10))/1;
e1=e;


a2=a1+1;
b2=b1+1;
c2=c1+1;
d2=d1+1;
e2=e1+1;

if (a2==10)
a2=0;
if (b2==10)
b2=0;
if (c2==10)
c2=0;
if (d2==10)
d2=0;
if (e2==10)
e2=0;


s=(a2*10000.0)+(b2*1000.0)+(c2*100.0)+(d2*10.0)+(e2);


printf("\nThe required result is %f",s);
}
