Program 1 using str functions

#include 'stdio.h'	
#include 'string.h'	
main()	
{		
	char name[80];/declare an array of characters 0-79
	printf("Enter in a name in lowercase\n");
	scanf( "%s", name );		
	strupr( name );
	printf(“name in uppercase=%s”, name);
	Strlwr( name );
	printf(“name in lowercase=%s”, name);
	strrev( name );
	printf(“reversed string=%s”, name);	
} 
            

Program 2 using str functions

/* Example program to use string functions*/ 
#include ' stdio.h ' 
#include ' string.h ' 
void main() 
{ 
    char s1[20],s2[20],s3[20]; 
	int x,l1,l2,l3; 
	printf(“Enter the strings”); 
	scanf(“%s%s”,s1,s2); 
	x=strcmp(s1,s2); 
	if(x!=0) 
	{  
	   printf(“\nStrings are not equal\n”); 
	   strcat(s1,s2); 
	 } 
    else
	   printf(“\nStrings are equal”); 
	   strcpy(s3,s1); 
	   l1=strlen(s1); 
	   l2=strlen(s2); 
	   l3=strlen(s3); 
	   printf(“\ns1=%s\t length=%d characters\n”,s1,l1); 
	   printf(“\ns2=%s\t length=%d characters\n”,s2,l2); 
	   printf(“\ns3=%s\t length=%d characters\n”,s3,l3); 
}
