CORRECT CODE:-
#include <stdio.h>
int main(){
    int num1,num2;
    char ch,a,b,c,d;
    
    printf("1. Enter 'a' for addition\n");
    printf("2. Enter 'b' for minus\n");
    printf("3. Enter 'c' for multipoltion\n");
    printf("4. Enter 'd' for divition\n");
    scanf("%c",&ch);
    
    printf("Enter the 1st number : ");
    scanf("%d",&num1);
    printf("Enter the 2nd number : ");
    scanf("%d",&num2);

    a = '+';
    b = '-';
    c = '*';
    d = '/';

    if(ch == 'a') {
        printf("Ans is %d\n",num1 + num2);
    }else if(ch == 'b') {
        printf("Ans is %d\n",num1 - num2);
    }else if(ch == 'c') {
        printf("Ans is %d\n",num1 * num2);
    }else if(ch == 'd') {
        printf("Ans is %d\n",num1 / num2);
    }else {
        printf("Incorrect input\n");
    }
    return 0;
}

Just Simply change %c to %s when you take value of ch from user and you dont have to writhe this

a = '+';
b = '-';
c = '*';
d = '/';
