Write a C program to delete n Characters from a given position in a given string.

//without using functions.

#include(stdio.h) // place this '<' & '>' instead of '(' & ')' before stdio.h
#include(string.h)
void main()
{
char st[20],temp[20];
int pos,i,j,ct=0,n;
clrscr();
printf("Enter the string:");
gets(st);
printf("\nEntre the index position:");
scanf("%d",&pos);
printf("\nEnter the no.of characters:");
scanf("%d",&n);
if(pos<=strlen(st)) {
for(i=0;i<=strlen(st);i++) {
if(i==pos)
{
for(j=0;st[i]!='\0';j++) // to store the 'st' in 'temp' from a giv pos
{
temp[j]=st[i];
i++;
}
temp[j]='\0';
i=pos;
//to delete the 'n' char and after restore the temp in st.
for(j=0;temp[j]!='\0';j++)
{
ct++;
if(ct>n)
{
st[i]=temp[j];
i++;
}
}
st[i]='\0';
}
}
printf("\n\nAfter deletion the string: %s",st);
}
else
printf("\nSorry, we cannot delete from that position.");
getch();
}
