Can anyone help me write a C function that goes through an input string and insert...

// b has the output string
change(char* a)
{
int ind=0,i;
char b[1000];
  
// as long as a has characters
while(*a)
{
// if the character is required symbol
if(*a == '<' || *a == '>' || *a == '|')
{
// adding spaces before and after
b[ind++] = ' ';
b[ind++] = *a;
b[ind++] = ' ';
}
else
{
b[ind++] = *a;
}
*a++;
ind++;
}
  
// printing output
for(i=0;i<ind;i++)
{
printf("%c",b[i]);
}
}

main()
{
// sample run
change("HELLO<WO|RLD>!");
}

Sample Output

HELLO < WO | RLD > !
