Description:

In this program we need to insert a string into another string from a specified position.

Algorithm:

Step 1: start

Step 2: read main string and sub string Step 3: find the length of main string(r) Step 4: find length of sub string(n)

Step 5: copy main string into sub string

Step 6: read the position to insert the sub string( p)

Step 7: copy sub string into main string from position p-1

Step 8: copy temporary string into main string from position p+n-1

Step 9: print the strings

Step 10: stop

Output:


1.enter first string: computer

2.enter second string: get
3.enter the position where the item has to be inserted:3 comgetputer

Conclusion :
