Implicit type conversion is done by the compiler by converting smaller data type into a larger data type.
For example, ASCII value of A=65.
In this program, we are giving character ‘A’ as input, now write a code to convert A to 65 which is its ASCII value.
Example
Following is the example to find ASCII value of uppercase character ‘A’ using implicit conversion −
#include<stdio.h>
int main(){
char character = 'A';
int number = 0, value;
value = character + number; //implicit conversion
printf("The ASCII value of A is: %d\n",value);
return 0;
}Output
The ASCII value of ‘A’ is 65. Using typecasting in C, the compiler automatically converts the character of char data type into the integer data type and the expression(value = character + number) becomes equal to 65 + 0 = 65
Therefore, the output would be 65.
The ASCII value of A is: 65
Example
Let us consider example by taking another character and see what is the ASCII value of that character.
#include<stdio.h>
int main(){
char character = 'P';
int number = 0, value;
value = character + number; //implicit conversion
printf("The ASCII value of P is: %d\n",value);
return 0;
}Output
The ASCII value of ‘P’ is 80. Using typecasting in C, the compiler automatically converts the character of char data type into the integer data type and the expression (value = character + number) becomes equal to 80 + 0 = 80
Therefore, the output would be 80.
The ASCII value of P is: 80
