How can I modify this C script so that instead of a single character d or w, it takes the specific string "Delta" or "Wye" as user input to choose either option in the script? I believe the only header that should need to be added is string.h, please don't add anything else I won't be able to use it. My script: #include #include int main(){ //4. Prompt the user for repetition of the process. char ch = 'y'; char network='a'; float za,zb,zc,zac,zbc,zcc,z1,z2,z3,z1c,z2c,z3c; float zaxb,zbxc,zaxc,zd,zdc,z1z3,z1z2,z2z3; float zaxbc,zbxcc,zaxcc,z1z3c,z1z2c,z2z3c,zt,ztc; while(ch=='y' || ch=='Y') { //1. ask the user whether it is a Delta or Wye network. printf("\nWhat kind of network? Enter D for delta or W for Wye network:\n\n"); scanf("%s",&network); //2. ask the user to type in values (for impedances) //3. make the conversion (Delta to Wye or Wye to Delta) //Delta Network ==> Wye if(network=='d'||network=='D'){ printf("\nWhat are the real values of the impedances Za,Zb,and Zc?\n\n"); printf("Za="); scanf("%f",&za); printf("Zb="); scanf("%f",&zb); printf("Zc="); scanf("%f",&zc); printf("\nWhat are the complex values of the impedances Za,Zb,and Zc?\n\n"); printf("Zac="); scanf("%f",&zac); printf("Zbc="); scanf("%f",&zbc); printf("Zcc="); scanf("%f",&zcc); zd=za+zb+zc; zdc=zac+zbc+zcc; zaxc=(za*zc)-(zac*zcc); zaxcc=(za*zcc)+(zc*zac); zaxb=(za*zb)-(zac*zbc); zaxbc=(za*zbc)+(zb*zac); zbxc=(zb*zc)-(zbc*zcc); zbxcc=(zb*zcc)+(zc*zbc); //zaxc/zd z1=((zaxc*zd)+(zaxcc*zdc))/((pow(zd,2)+(pow(zdc,2)))); //zaxb/zd z2=((zaxb*zd)+(zaxbc*zdc))/((pow(zd,2)+(pow(zdc,2)))); //zbxc/zd z3=((zbxc*zd)+(zbxcc*zdc))/((pow(zd,2)+(pow(zdc,2)))); //zaxcc/zdc z1c=((zaxcc*zd)-(zaxc*zdc))/((pow(zd,2)+pow(zdc,2))); //zaxbc/zdc z2c=((zaxbc*zd)-(zaxb*zdc))/((pow(zd,2)+pow(zdc,2))); //zbxcc/zdc z3c=((zaxcc*zd)-(zaxc*zdc))/((pow(zd,2)+pow(zdc,2))); printf("\nDelta values \nZa=%.2f+%.2fj, Zb=%.2f+%.2fj, Zc=%.2f+%.2fj\n\n",za,zac,zb,zbc,zc,zcc); printf("Correspond to Wye values \nZ1=%.2f+%.2fj, Z2=%.2f+%.2fj, Z3=%.2f+%.2fj\n\n",z1,z1c,z2,z2c,z3,z3c); } //Wye Network ==> Delta if(network=='w'||network=='W'){ printf("\nWhat are the real values of the impedances z1,z2,and z3?\n\n"); printf("Z1="); scanf("%f",&z1); printf("Z2="); scanf("%f",&z2); printf("Z3="); scanf("%f",&z3); printf("\nWhat are the complex values of the impedances z1,z2,and z3?\n\n"); printf("Z1c="); scanf("%f",&z1c); printf("Z2c="); scanf("%f",&z2c); printf("Z3c="); scanf("%f",&z3c); z1z2=((z1*z2)-(z1c*z2c)); z1z3=((z1*z3)-(z1c*z3c)); z2z3=((z2*z3)-(z2c*z3c)); z1z2c=((z1*z2c)+(z2*z1c)); z1z3c=((z1*z3c)+(z3*z1c)); z2z3c=((z2*z3c)+(z3*z2c)); zt=(z1z2+z1z3+z2z3); ztc=((z1z2c)+(z1z3c)+(z2z3c)); //za=zt/z3 //zb=zt/z1 //z3=zt/z2 za=(((zt*z3)+(ztc*z3c))/((pow(z3,2)))+(pow(z3c,2))); zb=(((zt*z1)+(ztc*z1c))/((pow(z1,2)))+(pow(z1c,2))); zc=(((zt*z2)+(ztc*z2c))/((pow(z2,2)))+(pow(z2c,2))); //zac=ztc/z3c //zbc=ztc/z1c //z3c=ztc/z2c zac=(((ztc*z3c)-(ztc*z3c))/((pow(z3,2)))+(pow(z3c,2))); zbc=(((ztc*z1c)-(ztc*z1c))/((pow(z1,2)))+(pow(z1c,2))); zcc=(((ztc*z2c)-(ztc*z2c))/((pow(z2,2)))+(pow(z2c,2))); printf("\nWye values \nZ1=%.2f+%.2fj, Z2=%.2f+%.2fj, Z3=%.2f+%.2fj\n\n",z1,z1c,z2,z2c,z3,z3c); printf("Correspond to Delta values \nZa=%.2f+%.2fj, Zb=%.2f+%.2fj, Zc=%.2f+%.2fj\n\n",za,zac,zb,zbc,zc,zcc); } printf("Enter Y to continue, enter any other character to stop the program.\n"); scanf(" %c",&ch); } return 0; }
