1. Reversing a string ALGORITHM:

Step 1: Start.

Step 2: declare s[1000], r[1000], begin, end, count ← 0. Step 3: print input a string
Step 4: read s
Step 5: using while loop with condition s[count] !← '\0' Count++

Step 6: End ← count - 1

Step 7: repeat until begin < count Step 8: r[begin] ← s[end]
end-- Step 9: r[begin] ← '\0' Step 10: print r
Step 11: print string reverse using library function Step 12: print enter a string to reverse
Step 13: read s
Step 14: reverse the string s using string function strrev(s). Step 15: print reversed string.
Step 16: Stop.

SOURCE CODE:

#include #include int main()

{
char s[1000], r[1000]; int begin, end, count = 0;

printf("Input a string\n"); gets(s);

// Calculating string length

while (s[count] != '\0') count++;

end = count - 1;
for (begin = 0; begin < count; begin++) { r[begin] = s[end];
end--;
}
r[begin] = '\0';

printf("%s\n", r);

// string reverse using a library function puts("String reverse using library function\n"); printf("Enter a string to reverse\n");
gets(s); strrev(s);
printf("Reverse of the string is \n%s\n", s); return 0;
}
