String dataString is read from input. If dataString does not contain character $\text{'}$c$\text{'}$ at or after index $4,$ then output "Character $\text{'}$c$\text{'}$ is not found at or after index $4."$ Otherwise, output:

"Starting at index $4,$ the first occurrence of character $\text{'}$c$\text{'}$ is at index $"$

the index of the first occurrence of $\text{'}$c$\text{'}$ at or after index $4$ in dataString

$"."$

End with a newline.

Ex: If the input is receipt, then the output is:

Character $\text{'}$c$\text{'}$ is not found at or after index $4.$

Ex: If the input is destruction, then the output is:

Starting at index $4,$ the first occurrence of character $\text{'}$c$\text{'}$ is at index $6.$ String dataString is read from input. If dataString does not contain character $\text{'}c\text{'}$ at or after index $4,$ then output

'Character $\text{'}c\text{'}$ is not found at or after index $4."$ Otherwise, output:

"Starting at index $4,$ the first occurrence of character $\text{'}$c$\text{'}$ is at index $"$

the index of the first occurrence of $\text{'}c\text{'}$ at or after index $4$ in dataString

End with a newline.

Ex: If the input is receipt, then the output is:

Character $\text{'}$c$\text{'}$ is not found at or after index $4.$

Ex: If the input is destruction, then the output is:

Starting at index $4,$ the first occurrence of character $\text{'}$c$\text{'}$ is at index $6.$
