C program to linear search for char data

Write a program to implements linear search for char data in 1D array. Use pointer to array for program.

 #include<stdio.h>
 int search(char*,char);
 int main()
 {
 	char str[100],ch;
 	int pos;
 	printf("Enter any String : "); 
 	gets(str);
 	printf("Enter any character for search in String : ");
 	scanf("%c",&ch);
 	pos=search(str,ch);
 	if(pos==1)
 	{
 		printf("Character found in string ");
	}
 	else
 	{
 		printf("Character not found in string ");
	}
	return 0;
 }
 int search(char *ptr,char c)
 {
 	int p=-1;
 	do
 	{
 		if(c==*ptr)
 		{
 			p=1;
 			break;
		}
		ptr++;
	}while(*ptr!='\0');
	return p;
 }
