Explanation: This program shows how to use a temporary variable to swap two numbers. First, the user provides us with two digits. In order to switch them, we first assign the value of b to a, store the value of an in a temporary variable, and then assign the value of b to a. This guarantees that no data is lost during the exchange of the two numbers’ values.<\/p>\n\n\n
\n#include <stdio.h>\n\nint main() {\n int a, b, temp;\n printf("Enter two numbers: ");\n scanf("%d %d", &a, &b);\n \n \/\/ Swapping process\n temp = a; \/\/ Store value of 'a' in 'temp'\n a = b; \/\/ Assign value of 'b' to 'a'\n b = temp; \/\/ Assign value stored in 'temp' (which is 'a') to 'b'\n \n printf("After swapping: a = %d, b = %d\\n", a, b);\n return 0;\n}\n\n<\/pre><\/div>\n\n\n<\/p>\n
