#include<stdio.h> #include<conio.h> #include<string.h> void main() { int i,n; char a[30]; clrscr(); printf(“Enter any string:”); gets(a); n=strlen(a); printf(“Reverse of string:”); for(i=(n-1);i>=0;–i) printf(“%c”,a[i]); getch(); }

C++ Program to convert first letter of each word of a string to uppercase and other to lowercase

#include<iostream.h> #include<conio.h> #include<stdio.h> #include<ctype.h> void main() { clrscr(); int i; char a[30]; cout<<“Enter a string:”; gets(a); for(i=0;a[i]!=’’;++i) { if(i==0) { if(islower(a[i])) a[i]=toupper(a[i]); } else { if(a[i]!=’ ‘) { if(isupper(a[i])) a[i]=tolower(a[i]); } else { i++; if(islower(a[i])) a[i]=toupper(a[i]); } } } cout<<“nnNew string is: “<<a; getch(); }
