Question:7
C program to take input for a string, further take input for a character to search, pass the string to a function, check and print whether the character is present in the string or not?
Sol:

#include<stdio.h>
void show(char *p,char ch)
{
	int z=0;
	while(*p!='\0')
	{
		if(*p==ch)
		{
			z=1;
			break;
		}
		p++;
	}
	if(z==0)
	printf("character is not present\n");
	else
	printf("character is present\n");
}
int main()
{
  char n[20],ch;
  printf("Enter any string ");
  gets(n);
  printf("Enter the character to search ");
  scanf("%c",&ch);
  show(n,ch);
  /* show(&n[0]); */
  return(0);
}

/* Output */
Enter any string computer
Enter the character to search m
character is present

Question:8
C program to take input for a string, further take input for a character to search, pass the string to a function, check and print whether the character is present in the string or not, if present print its position and total count?
Sol:

#include<stdio.h>
void show(char *p,char ch)
{
	int z=0,i=0;
	while(*p!='\0')
	{
		if(*p==ch)
		{
			z=z+1;
			printf("character found at %d position\n",i+1);
		}
		p++;
		i++;
	}
	if(z==0)
	printf("character is not present\n");
	else
	printf("character is present %d time\n",z);
}
int main()
{
  char n[20],ch;
  printf("Enter any string ");
  gets(n);
  printf("Enter the character to search ");
  scanf("%c",&ch);
  show(n,ch);
  /* show(&n[0]); */
  return(0);
}

/* Output */
Enter any string hello
Enter the character to search l
character found at 3 position
character found at 4 position
character is present 2 time
