Question:4
C program to input for a string, pass it to a function and display total lower case alphabets in the string.
Sol:

#include<stdio.h>
void show(char n[])
{
     int i=0,la=0;
     while(n[i]!='\0')
     {
          printf("%c\n",n[i]);
          if(n[i]>='a' && n[i]<='z')
          la++;
          
          i++;
     }
     printf("Length of string %d\n",i);
     printf("Total lower case alphabets in string %d\n",la);
}
int main()
{
     char n[30];
     printf("Enter any string ");
     gets(n);
     show(n);
}

/* Output */

Question:5
C program to input for a string, pass it to a function and display total upper case alphabets in the string.
Sol:

#include<stdio.h>
void show(char n[])
{
     int i=0,ua=0;
     while(n[i]!='\0')
     {
          printf("%c\n",n[i]);
          if(n[i]>='A' && n[i]<='Z')
          ua++;
          
          i++;
     }
     printf("Length of string %d\n",i);
     printf("Total Upper case alphabets in string %d\n",ua);
}
int main()
{
     char n[30];
     printf("Enter any string ");
     gets(n);
     show(n);
}

Question:6
C program to input for a string, pass it to a function and display total digits in the string.
Sol:

#include<stdio.h>
void show(char n[])
{
     int i=0,d=0;
     while(n[i]!='\0')
     {
          printf("%c\n",n[i]);
          if(n[i]>='0' && n[i]<='9')
          d++;
          
          i++;
     }
     printf("Length of string %d\n",i);
     printf("Total digits in string %d\n",d);
}
int main()
{
     char n[30];
     printf("Enter any string ");
     gets(n);
     show(n);
