How can we replace single character in a String

Single characters can be replaced in a string. Given the following declarations, several things are possible.

char str[25] = “cot”;

char ch = ‘u’;

char D[25] = “pat”;

• Replacing a single character using a char variable:
• D[1] = ch;

This would result in D containing “put”.

• Replacing a single character using a char literal:
• D[1] = ‘e’;

This would result in D containing “pet”.

• Replacing a single character using a single character from a string

variable:

• D[1] = str[1];

This would result in D containing “pot”.
