The Sum of two numbers in C print "4194429PS" for every number

Question

I've just begun my journey into programming with C Am writing a very simple beginner level program to add two numbers. The program works without errors it's the output that's very weird. It outputs the number "4194429PS" no matter what number I enter as input when am running the program and sticks a minus sign in front of it when I try to do difference of two numbers

Please anyone know what could be the problem

int main( void ){
int integer1;
int integer2;

printf( "Enter first integer\n" );
scanf("%d", &integer1);

printf( "Enter second integer\n" );
scanf("%d", &integer1);

int sum;
sum = integer1 + integer2;
printf("the sum of two numbers is %d", sum);

}

In "4194429PS" the `PS` part is the prompt string because you didn't print a new line after the sum => `printf("the sum of two numbers is %d\n", sum);` — phuclv, Mar 30 '22 at 03:27
Stupid me. Thanks so much. That thing was about to drive me crazy — Sopulu-Max, Mar 30 '22 at 06:49

You read integer 1 twice

int main( void ){
int integer1;
int integer2;

printf( "Enter first integer\n" );
scanf("%d", &integer1);

printf( "Enter second integer\n" );
scanf("%d", &integer1);   <<<<<====

int sum;
sum = integer1 + integer2;
printf("the sum of two numbers is %d", sum);

you need

int main( void ){
int integer1;
int integer2;
printf( "Enter first integer\n" );
scanf("%d", &integer1);

printf( "Enter second integer\n" );
scanf("%d", &integer2); <<<<===

int sum;
sum = integer1 + integer2;
printf("the sum of two numbers is %d", sum);

This should just be closed as a typo. – Barmar Mar 30 '22 at 00:24 — Barmar, Mar 30 '22 at 00:24
